12 years agortld: Compress FreeBSD CVSIDs
John Marino [Sat, 21 Jan 2012 11:08:45 +0000 (12:08 +0100)]
rtld: Compress FreeBSD CVSIDs

The FreeBSD repository is still handled by CVS, but its converted to
Subversion and from that, git.  Neither the svn nor git version feature
expanded $FreeBSD$ tags.  The only way to get this is to pull directly
from CVS which isn't convenient.

In the case of a few files, the only difference between the DragonFly
version and the FreeBSD version is the CVS tag.  As the main development
of rtld is happening on FreeBSD and since I've started collaborating
with FreeBSD developers on new dynamic linker features, we want to
actively keep our linkers synchronized.  Compressing the FreeBSD CVSID
tags makes that easier for me, the only person currently maintaining
the dynamic linker.  The usually-wrong expanded CVS tag wasn't providing
any useful information to me either.

Matthew Dillon [Mon, 16 Jan 2012 19:33:33 +0000 (11:33 -0800)]
kernel - Fix 3:00 a.m. crashes (deadlocks) related to HAMMER VM use

When memory is low and the pageout daemon needs to write things out we still
need to have at least some reserve to perform the supporting operations for
the pageout.  HAMMER is particularly memory intensive and could get into a
situation where insufficient reserve memory was available, deadlocking the
system.

With these changes DragonFly should run stable on systems with as little
as 256M of ram, and possibly a bit lower.

* The getblk/bread/bwrite/etc brelse/bqrelse sequence used to manage buffers
  had several bugs in it that prevented the low memory handling code from
  operating properly.  The b[q]relse() sequence was not properly detecting
  the low memory condition and freeing or caching the underlying VM pages
  (when possible).

* Also change the low memory test used by the buffer cache from 'severe'
  to 'min' in kern/vfs_bio.c.  We may be able to change this back to 'severe'
  at a later date with further testing.  These tests are in brelse(),
  bqrelse(), and vfs_vmio_release().

* Rewrite bio_page_alloc().  It effectively does the same thing that it did
  before but should operate more smoothly.  We also no longer try to recover
  pages from unrelated buffer cache buffers from this function, which could
  lead to deadlocks.  The warning kprintf is now also rate-limited.

* Add a buffer overload test in the hammer dedup ioctl.  A hammer dedup
  could cause a buffer cache deadlock by allowing too many dirty buffers
  to build up.

* Add a VM memory test to the core hammer flusher code that was previously
  only checking for the UNDO meta-data and buffer overload limits.  This
  is now done on a per-record basis and should prevent HAMMER from allocating
  too much memory during a flusher operation when the VM system is already
  too low on memory.

* Add some vm_wait_nominal() calls in critical I/O paths, but make sure we
  do not use these calls in any I/O path used by the HAMMER pageout code.

  Probably the most important path is the vm_object_page_clean*() code
  path, effectively called via either msync() or via the 30-60 second
  system sync.

* Properly bawrite() a buffer in hammer_vop_write() when IO_ASYNC is set
  (which is used by the pageout daemon), otherwise the pageout daemon will
  not be able to directly recover memory in low memory situations when
  paging to a HAMMER file mapped SHARED/RW.

bus error to segfault when an attempt to access protected memory is
made.  In the process of doing this, it was noticed that there were
differences between i386 and x86_64 as well as differences between
the actual and virtual kernels.

removed and some syncing between the divergent FreeBSD version was
made.  Some "#if 0" sections were removed.  The virtual kernels were
tested along with the real kernels.  A conservative approach was
taken as there seems to more cruft that could come out.

rtld: add RELRO support

"RELRO" means PLT (partial) or PLT+GOT (full) data is shifted to a
dedicated page by the linker which triggers the dynamic linker to
protect the page by setting the memory to read-only.  This feature
assists in detecting memory corruption and also prevents some types
of buffer overflow exploits.

Until now, this feature was only supported by Linux's glibc.  No BSD
had relro support in their dynamic linker.  I proposed the patch and
it was reviewed by a FreeBSD dynamic linker expert.  Attempts to
access protected data currently results in a bus error signal, but the
next commit will update the kernel trap files to cause the segfault
signal to be emitted instead.
