2014-04-07Retire kernel support for SO_DONTROUTE, this time without breakingMartin Pieuchot
localhost connections. The plan is to always use the routing table for addresses and routes resolutions, so there is no future for an option that wants to bypass it. This option has never been implemented for IPv6 anyway, so let's just remove the IPv4 bits that you weren't aware of. Tested a least by lteo@, guenther@ and chrisz@, ok mikeb@, benno@

struct ucred; struct process then directly links to the ucred Based on a discussion at c2k10 or so before noting that FreeBSD and NetBSD did this too. ok matthew@

2014-03-26Move p_emul and p_sigcode from proc to process.Philip Guenther
Tweak the handling of ktrace EMUL when changing ktracing: only generate one per process (not one per thread) and pass the correct proc pointer down to the VFS layer. Permit generating of NAMI and CSW records inside ktrace(2) itself. ok deraadt@ millert@

2014-02-13Instead of iterating over the per-interface list of addresses toMartin Pieuchot
find the link-layer address of an interface, use the pointer to the sockaddr_dl already present in the interface's descriptor. Tested for regression by pirofti@ with opera.
2014-02-12Eliminate the exit sig handling, which was only invokable via thePhilip Guenther
Linux-compat clone() syscall when *not* using CLONE_THREAD. pirofti@ confirms Opera runs in compat without this, so out it goes; one less hair to choke on in kern_exit.c ok tedu@ pirofti@
2014-01-23Try to cope better with void pointer to int usage cases.Paul Irofti
Use intptr_t for such cases. More casts/types should be improved in this file. Tested with syscall regression tests from IBM.

2014-01-20Threads can't be zombies, only processes, so change zombproc to zombprocess,Philip Guenther
make it a list of processes, and change P_NOZOMBIE and P_STOPPED from thread flags to process flags. Add allprocess list for the code that just wants to see processes. ok tedu@

2013-11-03Remove a bunch of a.out related macros.Paul Irofti
2013-11-03Regenerate.Paul Irofti
a.out removal led to linux_sys_uselib being obsoleted.
2013-11-03Remove a.out support from compat_linux(8).Paul Irofti
Tested with the syscall regression test suite from IBM and Opera. Requested by deraadt@.

2013-10-25Start to deal with the time_t change's effect on compat/linux:Philip Guenther
- add Linux versions of struct rusage, timeval, and itimerval and conversion functions for them - add Linux versions of getrusage(), gettimeofday(), {set,get}itimer(), and nanosleep() - fix various inconsistencies in naming of Linux versions of types and conversion functions - add mappings for LINUX_CLOCK_{PROCESS,THREAD}_CPUTIME_ID to the native versions Originally written months ago as part of the time_t work; long memory, prodding, and ok from pirofti@

2013-08-13Switch time_t, ino_t, clock_t, and struct kevent's ident and dataPhilip Guenther
members to 64bit types. Assign new syscall numbers for (almost all) the syscalls that involve the affected types, including anything with time_t, timeval, itimerval, timespec, rusage, dirent, stat, or kevent arguments. Add a d_off member to struct dirent and replace getdirentries() with getdents(), thus immensely simplifying and accelerating telldir/seekdir. Build perl with -DBIG_TIME. Bump the major on every single base library: the compat bits included here are only good enough to make the transition; the T32 compat option will be burned as soon as we've reached the new world are are happy with the snapshots for all architectures. DANGER: ABI incompatibility. Updating to this kernel requires extra work or you won't be able to login: install a snapshot instead. Much assistance in fixing userland issues from deraadt@ and tedu@ and build assistance from todd@ and otto@

Reviewed by guenther@.
2013-04-10futex: Prevent multiple futex pool initializations.Paul Irofti
This is a temporary (ugly) fix, the pool init call should be moved from linux_elf_probe into a better place.

2012-11-19Use a more descriptive name for the userland cas operation.Paul Irofti
Substitute atomic_ucas_32 with futex_atomic_ucas_int32 to make it obvious who's using this api. Suggested by and okay kettenis@.
2012-09-11Remove the 'OLF method' used for the transition from a.out to ELF andTheo de Raadt
for all the compat layers which are now gone. Linux compat still works because it always used another method in any case, and nothing looks at p_os anymore. ok jsing

2012-06-26Don't ignore SOCK_CLOEXEC and SOCK_NONBLOCK.Paul Irofti
CAVEATS: Assumes that a new socket can't have any of the FCNTLFLAGS set on it, which _is_ true, currently... (guenther@) Okay guenther@, deraadt@.
2012-06-20Copy the set_tls_base flag when forking.Paul Irofti
This enables the linux_child_return bits that set the TLS base in the newly forked process. Before this, processes that had the flag set would get a null pointer and segfault when trying to access the TLS area. Chased down and fixed by me. Turned into a proper one line diff by guenther@.
2012-06-19Count should always start from zero.Paul Irofti
Doesn't matter if we need to relocate or not. Makes sense to jasper@
2012-06-19Set the appropiate return value on futex wait.Paul Irofti
Okay jasper@
2012-06-19Avoid eternal sleep.Paul Irofti
Sleep on the actual data address and not on the stack address of the pointer to the data. Okay jasper@

2012-06-19Implement linux_sys_tgkill.Paul Irofti
Nobody calls linux_sys_tkill anymore so code for that is not needed. If this will become an issue in the future a simple wrapper will fix that. Okay jasper@.
2012-06-19Regenerate.Paul Irofti
2012-06-19Add dummies for the epoll and eventfd syscall families.Paul Irofti
Okay jasper@
2012-06-19Add socket type mask to filter out implementation specific flags.Paul Irofti
The newer glibc's, when creating a socket, add some higher bit flags to the type argument that are used for debug, statistics, profiling whatever. They are not useful and implementation specific. This is needed for DNS resolving, otherwise the nss library from glibc will always fail to do the right thing. Okay jasper@
2012-06-19Improve debug output and fix some style. No functional change.Paul Irofti
2012-06-19Change the pool_get() flags from WAITOK to NOWAIT.Paul Irofti
This avoids a potential lost-wakeup as pointed out by guenther@. Now the futex is locked all through the process and EAGAIN is returned on failure. Makes sense to guenther@.
2012-06-16compat_linux: Don't hold the lock while pool_get'ing with WAITOK.Paul Irofti
Okay jasper@.
2012-06-08RegeneratePaul Irofti
2012-06-08Remove the lack of gettid() implementation. Okay tedu@Paul Irofti
Looks right to jasper@ as well.
2012-05-25Change the KERN_FILE_BYPID and KERN_FILE_BYUID modes of the KERN_FILE2Philip Guenthe
sysctl() to be per-process instead of per-thread. This means the filedesc table has to really be per-process instead of per-thread, so make it an error for the linux clone() emulation to try to do otherwise. This removes pointless duplication in fstat's output. requested by jsing@ and deraadt@, ok matthew@ deraadt@
