* Revert r220032:linux compat: add SO_PASSCRED option with basic handlingAndriy Gapon2011-03-311-14/+0
| | | | | | | | | | | | | I have not properly thought through the commit. After r220031 (linux compat: improve and fix sendmsg/recvmsg compatibility) the basic handling for SO_PASSCRED is not sufficient as it breaks recvmsg functionality for SCM_CREDS messages because now we would need to handle sockcred data in addition to cmsgcred. And that is not implemented yet. Pointyhat to: avg Notes: svn path=/head/; revision=220186

* Linux' shm_open() fails because it wants to find some funky shmfsAlexander Leidinger2011-02-091-1/+9
| | | | | | | | | | | | | | | | | | | | | | | to construct the full pathname. It starts to search at the default mountpoint which is /dev/shm. If this fails it runs through fstab and searches for shmfs and tmpfs. Whatever it finds will be statfs()'ed to be checked for Linux' fs magic for shmfs (0x01021994). Ideally our tmpfs should deliver this fs magic to Linux processes, but as our tmpfs is considered to be an experimental feature we can not assume that there is always a tmpfs available. To make shared memory work in the Linuxulator, force the fs type of /dev/shm (which can be a symlink) to match what Linux expects. The user is responsible (info has to be added to the linux base ports and the docs) to setup a suitable link for /dev/shm.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | on FreeBSD (amd64), invocations of "javac" (or "java") eventually end with the output of "Killed" and exit code 137. This is caused by: 1. After calling exec() in multithreaded linux program threads are not destroyed and continue running. They get killed after program being executed finishes. 2. linux_exit_group doesn't return correct exit code when called not from group leader. Which happens regularly using sun jvm. The submitters fix this in a similar way to how NetBSD handles this. I took the PRs away from dchagin, who seems to be out of touch of this since a while (no response from him).

| | | | | | | | | | | | | | | | | | | | | | | | | Intention of this commit is to let us take a full advantage of libusb(8) ported to Linux. This decreases a possibility of getting any collisions within ioctl() "command" space, especially with relation to LINUX_SNDCTL_SEQ... stuff. Basically, we provide commands, that will be mapped in the kernel to correct ones and forward those to the USB layer.

* Rename st_*timespec fields to st_*tim for POSIX 2008 compliance.Ed Schouten2010-03-281-9/+18
| | | | | | | | | | | | | | | | | | A nice thing about POSIX 2008 is that it finally standardizes a way to obtain file access/modification/change times in sub-second precision, namely using struct timespec, which we already have for a very long time. Unfortunately POSIX uses different names. This commit adds compatibility macros, so existing code should still build properly. Also change all source code in the kernel to work without any of the compatibility macros. This makes it all a less ambiguous. I am also renaming st_birthtime to st_birthtim, even though it was a local extension anyway. It seems Cygwin also has a st_birthtim. Notes: svn path=/head/; revision=205792
