Posix spawn fixes: - split the file actions allocation and freeing into separate functions - use pnbuf - don't play games with pointers (partially freeing stuff etc), only check fa and sa and free as needed using the same code. - use copyinstr properly - KM_SLEEP allocation can't fail - if path allocation failed midway, we would be possibily freeing userland strings. - use sizeof(*var) instead sizeof(type)

More posix_spawn fallout: Fix a kmem_alloc() call with zero size (PR kern/46038), allow file actions to be passed, even if empty. Rearange p_reflock locking for the child, avoid a double free in an error case, avoid a memory leak in another error case - all pointed out by yamt. During blocking operations early in the child borrow the kernel vmspace (as suggested by yamt).

First step of random number subsystem rework described in <20111022023242.BA26F14A158@mail.netbsd.org>. This change includes the following: An initial cleanup and minor reorganization of the entropy pool code in sys/dev/rnd.c and sys/dev/rndpool.c. Several bugs are fixed. Some effort is made to accumulate entropy more quickly at boot time. A generic interface, "rndsink", is added, for stream generators to request that they be re-keyed with good quality entropy from the pool as soon as it is available. The arc4random()/arc4randbytes() implementation in libkern is adjusted to use the rndsink interface for rekeying, which helps address the problem of low-quality keys at boot time. An implementation of the FIPS 140-2 statistical tests for random number generator quality is provided (libkern/rngtest.c). This is based on Greg Rose's implementation from Qualcomm. A new random stream generator, nist_ctr_drbg, is provided. It is based on an implementation of the NIST SP800-90 CTR_DRBG by Henric Jungheim. This generator users AES in a modified counter mode to generate a backtracking-resistant random stream. An abstraction layer, "cprng", is provided for in-kernel consumers of randomness. The arc4random/arc4randbytes API is deprecated for in-kernel use. It is replaced by "cprng_strong". The current cprng_fast implementation wraps the existing arc4random implementation. The current cprng_strong implementation wraps the new CTR_DRBG implementation. Both interfaces are rekeyed from the entropy pool automatically at intervals justifiable from best current cryptographic practice. In some quick tests, cprng_fast() is about the same speed as the old arc4randbytes(), and cprng_strong() is about 20% faster than rnd_extract_data(). Performance is expected to improve. The AES code in src/crypto/rijndael is no longer an optional kernel component, as it is required by cprng_strong, which is not an optional kernel component. The entropy pool output is subjected to the rngtest tests at startup time; if it fails, the system will reboot. There is approximately a 3/10000 chance of a false positive from these tests. Entropy pool _input_ from hardware random numbers is subjected to the rngtest tests at attach time, as well as the FIPS continuous-output test, to detect bad or stuck hardware RNGs; if any are detected, they are detached, but the system continues to run. A problem with rndctl(8) is fixed -- datastructures with pointers in arrays are no longer passed to userspace (this was not a security problem, but rather a major issue for compat32). A new kernel will require a new rndctl. The sysctl kern.arandom() and kern.urandom() nodes are hooked up to the new generators, but the /dev/*random pseudodevices are not, yet. Manual pages for the new kernel interfaces are forthcoming.

- Fix a few possible locking issues in execve1() and exit1(). Add a note that scheduler locks are special in this regard - adaptive locks cannot be in the path due to turnstiles. Randomly spotted/reported by uebayasi@. - Remove unused lwp_relock() and replace lwp_lock_retry() by simplifying lwp_lock() and sleepq_enter() a little. - Give alllwp its own cache-line and mark lwp_cache pointer as read-mostly.

Abolish the SAVENAME and HASBUF flags. There is now always a buffer, so the path in a struct componentname is now always valid during VOP calls.

Abolish struct componentname's cn_pnbuf. Use the path buffer in the pathbuf object passed to namei as work space instead. (For now a pnbuf pointer appears in struct nameidata, to support certain unclean things that haven't been fixed yet, but it will be going away in the future.) This removes the need for the SAVENAME and HASBUF namei flags.

Introduce struct pathbuf. This is an abstraction to hold a pathname and the metadata required to interpret it. Callers of namei must now create a pathbuf and pass it to NDINIT (instead of a string and a uio_seg), then destroy the pathbuf after the namei session is complete. Update all namei call sites accordingly. Add a pathbuf(9) man page and update namei(9). The pathbuf interface also now appears in a couple of related additional places that were passing string/uio_seg pairs that were later fed into NDINIT. Update other call sites accordingly.

many changes for COMPAT_LINUX: - update the linux syscall table for each platform. - support new-style (NPTL) linux pthreads on all platforms. clone() with CLONE_THREAD uses 1 process with many LWPs instead of separate processes. - move the contents of sys__lwp_setprivate() into a new lwp_setprivate() and use that everywhere. - update linux_release[] and linux32_release[] to "2.6.18". - adjust placement of emul fork/exec/exit hooks as needed and adjust other emul code to match. - convert all struct emul definitions to use named initializers. - change the pid allocator to allow multiple pids to refer to the same proc. - remove a few fields from struct proc that are no longer needed. - disable the non-functional "vdso" code in linux32/amd64, glibc works fine without it. - fix a race in the futex code where we could miss a wakeup after a requeue operation. - redo futex locking to be a little more efficient.

Remove the nameidata from struct exec_package. It was used only for two things: passing an argument to check_exec, which is better done explicitly, and handing back the resolved pathname generated by namei, which we can make an explicit slot for in struct exec_package instead. While here, perform some related tidyup, and store the kernel-side copy of the path to the executable as well as the pointer into userspace. (But the latter should probably be removed in the future.)

- add new RLIMIT_AS (aka RLIMIT_VMEM) resource that limits the total
address space available to processes. this limit exists in most other
modern unix variants, and like most of them, our defaults are unlimited.
remove the old mmap / rlimit.datasize hack.
- adds the VMCMD_STACK flag to all the stack-creation vmcmd callers.
it is currently unused, but was added a few years ago.
- add a pair of new process size values to kinfo_proc2{}. one is the
total size of the process memory map, and the other is the total size
adjusted for unused stack space (since most processes have a lot of
this...)
- patch sh, and csh to notice RLIMIT_AS. (in some cases, the alias
RLIMIT_VMEM was already present and used if availble.)
- patch ps, top and systat to notice the new k_vm_vsize member of
kinfo_proc2{}.
- update irix, svr4, svr4_32, linux and osf1 emulations to support
this information. (freebsd could be done, but that it's best left
as part of the full-update of compat/freebsd.)
this addresses PR 7897. it also gives correct memory usage values,
which have never been entirely correct (since mmap), and have been
very incorrect since jemalloc() was enabled.
tested on i386 and sparc64, build tested on several other platforms.
thanks to many folks for feedback and testing but most espcially
chuq and yamt for critical suggestions that lead to this patch not
having a special ugliness i wasn't happy with anyway :-)

Network protocol interrupts can now block on locks, so merge the globals proclist_mutex and proclist_lock into a single adaptive mutex (proc_lock). Implications: - Inspecting process state requires thread context, so signals can no longer be sent from a hardware interrupt handler. Signal activity must be deferred to a soft interrupt or kthread. - As the proc state locking is simplified, it's now safe to take exit() and wait() out from under kernel_lock. - The system spends less time at IPL_SCHED, and there is less lock activity.

For PIE executables(*) randomization is enabled for:
1. The program itself
2. All shared libraries
3. The data segment
4. The stack
(*) To generate a PIE executable:
- compile everything with -fPIC
- link with -shared-libgcc -Wl,-pie
This feature is experimental, and might change. To use selectively add
options PAX_ASLR=0

Currently we are using 12 bits for the stack, program, and data segment and
16 or 24 bits for mmap, depending on __LP64__.

Change the way that emulations locate files within the emulation root to avoid having to allocate space in the 'stackgap' - which is very LWP unfriendly. The additional code for non-emulation namei() is trivial, the reduction for the emulations is massive. The vnode for a processes emulation root is saved in the cwdi structure during process exec. If the emulation root the TRYEMULROOT flag are set, namei() will do an initial search for absolute pathnames in the emulation root, if that fails it will retry from the normal root. ".." at the emulation root will always go to the real root, even in the middle of paths and when expanding symlinks. Absolute symlinks found using absolute paths in the emulation root will be relative to the emulation root (so /usr/lib/xxx.so -> /lib/xxx.so links inside the emulation root don't need changing). If the root of the emulation would be returned (for an emulation lookup), then the real root is returned instead (matching the behaviour of emul_lookup, but being a cheap comparison here) so that programs that scan "../.." looking for the root dircetory don't loop forever. The target for symbolic links is no longer mangled (it used to get the CHECK_ALT_xxx() treatment, so could get /emul/xxx prepended). CHECK_ALT_xxx() are no more. Most of the change is deleting them, and adding TRYEMULROOT to the flags to NDINIT(). A lot of the emulation system call stubs could now be deleted.

okay, since there was no way to divide this to two commits, here it goes.. introduce fileassoc(9), a kernel interface for associating meta-data with files using in-kernel memory. this is very similar to what we had in veriexec till now, only abstracted so it can be used more easily by more consumers. this also prompted the redesign of the interface, making it work on vnodes and mounts and not directly on devices and inodes. internally, we still use file-id but that's gonna change soon... the interface will remain consistent. as a result, veriexec went under some heavy changes to conform to the new interface. since we no longer use device numbers to identify file-systems, the veriexec sysctl stuff changed too: kern.veriexec.count.dev_N is now kern.veriexec.tableN.* where 'N' is NOT the device number but rather a way to distinguish several mounts. also worth noting is the plugging of unmount/delete operations wrt/fileassoc and veriexec. tons of input from yamt@, wrstuden@, martin@, and christos@.

Split sys_execve() and add execve1() that does most of the work, and takes
as an argument a function that will retrieve an element of the pointer
arrays in user space. This allows COMPAT_NETBSD32 to share the code for
the emulated version of execve(2), and fixes various issues that came from
the slow drift between the two implementations.
Note: when splitting up a syscall function, I'll use two different ways
of naming the resulting helper function. If it stills does
copyin/out operations, it will be named <syscall>1(). If it does
not (as it was the case for get/setitimer), it will be named
do<syscall>.

Rototill of the verified exec functionality.
* We now use hash tables instead of a list to store the in kernel
fingerprints.
* Fingerprint methods handling has been made more flexible, it is now
even simpler to add new methods.
* the loader no longer passes in magic numbers representing the
fingerprint method so veriexecctl is not longer kernel specific.
* fingerprint methods can be tailored out using options in the kernel
config file.
* more fingerprint methods added - rmd160, sha256/384/512
* veriexecctl can now report the fingerprint methods supported by the
running kernel.
* regularised the naming of some portions of veriexec.

Fix some things regarding COMPAT_NETBSD32 and limits/VM addresses. * For sparc64 and amd64, define *SIZ32 VM constants. * Add a new function pointer to struct emul, pointing at a function that will return the default VM map address. The default function is uvm_map_defaultaddr, which just uses the VM_DEFAULT_ADDRESS macro. This gives emulations control over the default map address, and allows things to be mapped at the right address (in 32bit range) for COMPAT_NETBSD32. * Add code to adjust the data and stack limits when a COMPAT_NETBSD32 or COMPAT_SVR4_32 binary is executed. * Don't use USRSTACK in kern_resource.c, use p_vmspace->vm_minsaddr instead (emulations might have set it differently) * Since this changes struct emul, bump kernel version to 3.99.2 Tested on amd64, compile-tested on sparc64.

Add a sigfilter emulation hook. It is used at the beginning of kpsignal2() so that a specific emulation has the oportunity to filter out some signals. if sigfilter returns 0, then no signal is sent by kpsignal2(). There is another place where signals can be generated: trapsignal. Since this function is already an emulation hook, no call to the sigfilter hook was introduced in trapsignal. This is needed to emulate the softsignal feature in COMPAT_DARWIN (signals sent as Mach exception messages)

add support for non-executable mappings (where the hardware allows this) and make the stack and heap non-executable by default. the changes fall into two basic catagories: - pmap and trap-handler changes. these are all MD: = alpha: we already track per-page execute permission with the (software) PG_EXEC bit, so just have the trap handler pay attention to it. = i386: use a new GDT segment for %cs for processes that have no executable mappings above a certain threshold (currently the bottom of the stack). track per-page execute permission with the last unused PTE bit. = powerpc/ibm4xx: just use the hardware exec bit. = powerpc/oea: we already track per-page exec bits, but the hardware only implements non-exec mappings at the segment level. so track the number of executable mappings in each segment and turn on the no-exec segment bit iff the count is 0. adjust the trap handler to deal. = sparc (sun4m): fix our use of the hardware protection bits. fix the trap handler to recognize text faults. = sparc64: split the existing unified TSB into data and instruction TSBs, and only load TTEs into the appropriate TSB(s) for the permissions. fix the trap handler to check for execute permission. = not yet implemented: amd64, hppa, sh5 - changes in all the emulations that put a signal trampoline on the stack. instead, we now put the trampoline into a uvm_aobj and map that into the process separately. originally from openbsd, adapted for netbsd by me.

- Introduce a e_fault field in struct proc to provide emulation specific memory fault handler. IRIX uses irix_vm_fault, and all other emulation use NULL, which means to use uvm_fault. - While we are there, explicitely set to NULL the uninitialized fields in struct emul: e_fault and e_sysctl on most ports - e_fault is used by the trap handler, for now only on mips. In order to avoid intrusive modifications in UVM, the function pointed by e_fault does not has exactly the same protoype as uvm_fault: int uvm_fault __P((struct vm_map *, vaddr_t, vm_fault_t, vm_prot_t)); int e_fault __P((struct proc *, vaddr_t, vm_fault_t, vm_prot_t)); - In IRIX share groups, all the VM space is shared, except one page. This bounds us to have different VM spaces and synchronize modifications to the VM space accross share group members. We need an IRIX specific hook to the page fault handler in order to propagate VM space modifications caused by page faults.

From OpenBSD, via FreeBSD: If a set{u,g}id binary is invoked with fd < 3
closed, open those fds to /dev/null.
XXX: This needs to be fixed in a better way. The kernel should not need to
know about /dev/null or special case 0, 1, 2.

In check_exec(), don't bother checking P_TRACED along with
MNT_NOSUID, just check MNT_NOSUID to clear the S{U,G}ID bits
in the attributes for the vnode we're about to exec.
We now check P_TRACED right before we would actually perform
the s{u,g}id function in the exec code.
This closes a race condition between exec of a setuid binary
and ptrace(2).

Added two flags to emulation packages: EMUL_BSD_ASYNCIO_PIPE notes that the emulated binaries expect the original BSD pipe behavior for asynchronous I/O, which is to fire SIGIO on read() and write(). OSes without this flag do not expect any SIGIO to be fired on read() and write() for pipes, even when async I/O was requested. As far as we know, the OSes that need EMUL_BSD_ASYNCIO_PIPE are NetBSD, OSF/1 and Darwin. EMUL_NO_SIGIO_ON_READ notes that the emulated binaries that requested asynchrnous I/O expect the reader process to be notified by a SIGIO, but not the writer process. OSes without this flag expect the reader and the writer to be notified when some data has arrived or when some data have been read. As far as we know, the OSes that need EMUL_NO_SIGIO_ON_READ are Linux and SunOS.

Introduce 2 new flags in types.h: * __HAVE_SYSCALL_INTERN. If this is defined, e_syscall is replaced by e_syscall_intern, which is called at key places in the kernel. This can be used to set a MD syscall handler pointer. This obsoletes and replaces the *_HAS_SEPARATED_SYSCALL flags. * __HAVE_MINIMAL_EMUL. If this is defined, certain (deprecated) elements in struct emul are omitted.

restructure struct emul and execsw, in preparation to make emulations LKMable:
* move all exec-type specific information from struct emul to execsw[] and
provide single struct emul per emulation
* elf:
- kern/exec_elf32.c:probe_funcs[] is gone, execsw[] how has one entry
per emulation and contains pointer to respective probe function
- interp is allocated via MALLOC() rather than on stack
- elf_args structure is allocated via MALLOC() rather than malloc()
* ecoff: the per-emulation hooks moved from alpha and mips specific code
to OSF1 and Ultrix compat code as appropriate, execsw[] has one entry per
emulation supporting ecoff with appropriate probe function
* the makecmds/probe functions don't set emulation, pointer to emulation is
part of appropriate execsw[] entry
* constify couple of structures

Reduce use of curproc in several places: - Change ktrace interface to pass in the current process, rather than p->p_tracep, since the various ktr* function need curproc anyway. - Add curproc as a parameter to mi_switch() since all callers had it handy anyway. - Add a second proc argument for inferior() since callers all had curproc handy. Also, miscellaneous cleanups in ktrace: - ktrace now always uses file-based, rather than vnode-based I/O (simplifies, increases type safety); eliminate KTRFLAG_FD & KTRFAC_FD. Do non-blocking I/O, and yield a finite number of times when receiving EWOULDBLOCK before giving up. - move code duplicated between sys_fktrace and sys_ktrace into ktrace_common. - simplify interface to ktrwrite()

Remplace kern.shortcorename sysctl with a more flexible sheme, core filename format, which allow to change the name of the core dump, and to relocate it in a directory. Credits to Bill Sommerfeld for giving me the idea :) The default core filename format can be changed by options DEFCORENAME and/or kern.defcorename Create a new sysctl tree, proc, which holds per-process values (for now the corename format, and resources limits). Process is designed by its pid at the second level name. These values are inherited on fork, and the corename fomat is reset to defcorename on suid/sgid exec. Create a p_sugid() function, to take appropriate actions on suid/sgid exec (for now set the P_SUGID flag and reset the per-proc corename). Adjust dosetrlimit() to allow changing limits of one proc by another, with credential controls.

Substantial signal handling changes: * Increase the size of sigset_t to accomodate 128 signals -- adding new versions of sys_setprocmask(), sys_sigaction(), sys_sigpending() and sys_sigsuspend() to handle the changed arguments. * Abstract the guts of sys_sigaltstack(), sys_setprocmask(), sys_sigaction(), sys_sigpending() and sys_sigsuspend() into separate functions, and call them from all the emulations rather than hard-coding everything. (Avoids uses the stackgap crap for these system calls.) * Add a new flag (p_checksig) to indicate that a process may have signals pending and userret() needs to do the full (slow) check. * Eliminate SAS_ALTSTACK; it's exactly the inverse of SS_DISABLE. * Correct emulation bugs with restoring SS_ONSTACK. * Make the signal mask in the sigcontext always use the emulated mask format. * Store signals internally in sigaction structures, rather than maintaining a bunch of little sigsets for each SA_* bit. * Keep track of where we put the signal trampoline, rather than figuring it out in *_sendsig(). * Issue a warning when a non-emulated sigaction bit is observed. * Add missing emulated signals, and a native SIGPWR (currently not used). * Implement the `not reset when caught' semantics for relevant signals. Note: Only code touched by the i386 port has been modified. Other ports and emulations need to be updated.

a program being exec'd *must* cause *some* exec commands to be invoked; if it doesn't there's a problem in the kernel, because a program with no exec commands run will have no address space except the stack, and i don't think it's valid to have a "run from stack only" exec type, so panic. if need for that case comes up later, it can be changed...

fixed bug where extra spaces at the end of a shell name would cause shell scripts to be executed incorrectly. shells would receive an *empty* arg for name of script, open it, the kernel would say "oh, that's ." or something similar, and the results would be interesting... found, diagnosed, and killed by me.
