fvdl 3c9ce57651 Don't try to copy an mbuf that may have been freed in case of an error. 1999-07-30 09:46:24 +00:00
sommerfeld c1ecf66965 kern/5591: Fix race in the NFS socket code during umount -f and system
shutdown:

During an unmount, wake up all the processes which are waiting to lock
the socket for receive, and wait for them (and the process blocked in
soreceive, if any) to go away before blowing away the socket and the
mount structure.

fvdl fb1a849339 Use different names for the "nfscon" label to tsleep(), so that it can
be seen in which one a process is sleeping.

mycroft fb526e055c 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.

fvdl 0c8ab9044c Only take the receive lock before disconnecting when doing it from
nfs_decode_args. Otherwise we might just end up locking against ourselves.

XXX workaround, will do ok for now. Proper fix forthcoming.
1998-01-30 22:44:13 +00:00
fvdl e46f160a4a Make sure the receive lock is taken when disconnecting a socket. Also
change a check for a 'connected' socket to use the socket rather than
the mount flags.

From Matthias Drochner.

fvdl 7f7d814e67 * New directory entry caching system. Provides full caching of any
directory cookie that may be thrown back at us from userspace, up
  to a size limit. Fixes double entry problem.
* Split flags for internal and external use in the NFS mount structure.
* Fix some buffer structure fields that weren're being used correctly.
* Fix missing directory cache inval call in nfs_open.
* Limit on NFS_DIRBLKSIZ no longer needed, bumped to the more reasonable
  value of 8k.
* Various other things that I forget, all related to the dir caching
  somehow, though.

gwr 248eff8eee Temporary work-around for PR kern/3579 (from Jonathan Stone). 1997-05-22 18:20:06 +00:00
fvdl fe28924160 * If nfs_reconnect fails, be sure to release the sndlock, otherwise no
other requests will get through and the mount point will be effectively dead.
  This could happen for mounts using TCP and -i and/or -s.
* Reserve enough space for UDP sockets. Fixes PR 3008, from Naofumi Honda.

fvdl b4e49cf0e9 Avoid nfsiods acquiring/releasing a lock, then acquiring it again, before
anyone else can get to it, by checking if a reply was received, and it
has thus become unnecessary to take the lock. From FreeBSD.

XXX I don't really like this, "locks" potentially suffer from the same
problem throughout the whole kernel; they should probably be FIFO everywhere.

fvdl dce1770311 Fixes from BSDI (thanks go to Keith Bostic). Original RCS messages:
date: 1995/11/30 20:37:03;  author: cp;  state: Exp;  lines: +25 -14
Change splsoftclock() to splnet();
Make nfsrv_getstream create two copies of data when
splitting up an mbuf rather than two references to the
same external buffer. The symptom this fixes is client
hangs.

date: 1997/02/10 18:41:13;  author: cp;  state: Exp;  lines: +4 -1
Make nfs_realign go away on sparc and add functionality to nfsm_disct.

1997-02-09 21:19:04 +00:00
fvdl 64fcae7bcb * Make sure a new socket is created when switching to/from NOCONN with
a mount
* Add extra printf statements to hopefully get some more info on lockups,
  specifically when a send error is ignored.
