svn commit: r367445 - head/sys/kern
Author: trasz
Date: Sat Nov 7 13:09:51 2020
New Revision: 367445
URL: https://svnweb.freebsd.org/changeset/base/367445
Log:
Move TDB_USERWR check under 'if (traced)'.
If we hadn't been traced in the first place when syscallenter()
started executing, we can ignore TDB_USERWR. TDB_USERWR can get set,
sure, but if it does, it's because the debugger raced with the syscall,
and it cannot depend on winning that race.

Two reasons. First, from what I can tell this is an artificial limitation which serves no purpose. I thought it was to prevent some kind of deadlock between vnodes, so I asked kib@, and he mentioned removing that very limitation from the kernel code; thus, it looks to me like a historical leftover. Second, I've stumbled upon this when trying to nullfs-mount '/' on '/compat/ubuntu/bsd/', which would be useful for autochroot functionality, when (or if) it becomes a thing. ___ svn-src-head@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/svn-src-head To unsubscribe, send any mail to "svn-src-head-unsubscr...@freebsd.org"

svn commit: r366812 - head/sys/dev/iscsi
Author: trasz
Date: Sun Oct 18 16:30:49 2020
New Revision: 366812
URL: https://svnweb.freebsd.org/changeset/base/366812
Log:
If the SIM freezes the queue at exactly the wrong moment, after
another thread has started to send in a CCB and already checked
the queue wasn't frozen, we would end up with iscsi_action()
being called despite the queue is now frozen.
Add a check to make sure this doesn't happen . Perhaps this should
be fixed at the CAM level instead, but given how the send queue and
SIM are governed by two separate mutexes, it is somewhat hard to do.

svn commit: r366756 - head/sys/compat/linux
Author: trasz
Date: Fri Oct 16 11:23:30 2020
New Revision: 366756
URL: https://svnweb.freebsd.org/changeset/base/366756
Log:
Set default stack size for Linux apps to 8MB. This matches Linux'
defaults, makes core files smaller, and fixes applications which use
pthread_join(3) in a wrong way, namely Steam.
This is based on a patch submitted by Jason Yang, which I've reworked
to set the limit instead of only changing the value reported (which
is enough to fix the bug for Linux pthreads, but could be confusing).

Author: trasz
Date: Tue Sep 29 11:48:22 2020
New Revision: 366251
URL: https://svnweb.freebsd.org/changeset/base/366251
Log:
Build debug kernels with -O2.
LLVM 11 changed the meaning of '-O' from '-O2' to '-O1', which resulted
in debug kernels (with 'makeoptions DEBUG=-g') being built with inlining
disabled, causing severe performance hit.
The -O2 was already being used for building amd64, powerpc, and powerpcspe.

Move SV_ABI_ERRNO translation into linux-specific code, to simplify
the syscall path and declutter it a bit. No functional changes intended.

New Revision: 365040
URL: https://svnweb.freebsd.org/changeset/base/365040
Log:
Fix string overflow that could occur during redirection due to passing
the wrong length to strlcpy(3). It looks like it could overflow into
the next field, isc_user, which is properly long to accomodate for it;
I don't think it could cause any harm other than breaking the connection.

The main chunk of stats(3) source is shared between libstats(3)
and the kernel. Thus, DIAGNOSTICS means the same thing: it's not
the usual assertions, but an additional debugging mechanism that's
supposed to be off by default. Except that we don't have a global
knob to turn "userland DIAGNOSTICS" on, so libstats(3) uses its own.
We probably shouldn't be overriding WITHOUT_ASSERT_DEBUG, though.

New Revision: 363093
URL: https://svnweb.freebsd.org/changeset/base/363093
Log:
Make linux stat(2) return the same st_dev for every devfs instance.
The reason for this is to work around an idiosyncrasy of glibc
getttynam(3) implementation: it checks whether st_dev returned for
fd 0 is the same as st_dev returned for the target of /proc/self/fd/0
symlink, and with linux chroots having their own devfs instance,
the check will fail if you chrooted into it.

Log:
Fix Linux recvmsg(2) when msg_namelen returned is 0. Previously
it would fail with EINVAL, breaking some of the Python regression
tests.
While here, cap the user-controlled message length.
Note that the code doesn't seem to be copying out the new length
in either (success or failure) case. This will be addressed separately.

svn commit: r362833 - head/sys/compat/linux
Author: trasz
Date: Wed Jul 1 10:37:08 2020
New Revision: 362833
URL: https://svnweb.freebsd.org/changeset/base/362833
Log:
Rework linux accept(2). This makes the code flow easier to follow,
and fixes a bug where calling accept(2) could result in closing fd 0.
Note that the code still contains a number of problems: it makes
assumptions about l_sockaddr_in being the same as sockaddr_in,
the EFAULT-related code looks like it doesn't work at all, and the
socket type check is racy. Those will be addressed later on;
I'm trying to work in small steps to avoid breaking one thing while
fixing another.
It fixes Redis, among other things.
