than 32k.
A bootconf file is normally only a few hundred bytes long. If it is
much bigger than expected, we can't load it into an 8086 real mode
segment anyway.
Much more to the point, in the pxeboot case, someone may have
configured their dhcpd to return the filename for the kernel, not
realizing that the filename is now for boot.cfg which didn't used to
be the case. If we try to load the kernel here, thinking it is
boot.cfg by accident, the boot loader will die ignominiously and
without much of an error message, so we don't want to do that.
This needs to be pulled up to 5.0 if 5.0 has all this machinery
-- I'm not sure whether it does.
Fix some of the races (but probably not all of them) in the NFS server code.
nfssvc_nfsd(): change a splsoftclock()/spx() to mutex_enter/exit(&nfsd_lock)
(I guess it was forgotten when the nfsd code was made SMP safe)
m_freem(nd_nam) in nfsrv_slpderef() instead of nfsrv_zapsock() to
avoid possible use after free in nfssvc_nfsd()
Fix nfsrv_slpderef() to not release nfsd_lock before testing SLP_VALID
and reaquiring it just after. This could cause a use after free
of the slp if one thread is in nfsrv_slpderef() and the other one grabs
slp from nfssvc_sockpending and zap it.
nfsrv_rename() can exit without calling genfs_renamelock_exit() because
the nfsm_reply() can do return (0) on error.
Change nfsm_reply to use 'error = 0; goto nfsmout' instead.
Fix a few place so it's safe to goto nfsmout from nfsm_reply, or other
macros calling it.
As a side effect it could fix a missing vrele(dirp) in various place where
nfsm_reply could return(0).
when installing hard links. They have no effect except when using a
metalog, in which case the information is added to the metalog. In
the future, these variables may be replaced by a method for explicitly
recording hard links in a metadata log.
Also change a few things that called ${INSTALL_LINK} without going
through bsd.links.mk.
Reviewed by perry and joerg. This should fix PR 24457 and PR 41155.
Make copyin(9) and copyout(9) work with 64KB or larger data blocks.
Fixes broken pipe(2) problem mentioned in PR port-vax/41139. Ok'ed by ragge@.
Should be pulled up to netbsd-5.
- Remove all longjmp(3) calls from signal handlers. Instead, we post
to an internal signal queue and check that periodically. All signal
related code is now in sig.c, except for the SIGCHLD handler which
remains in popen.c as it is intimately tied to routines there.
- Handle SIGPIPE in type1() regardless of mime support, or else the
handler in execute() will prevent our error code from being returned
resulting in 'sawcom' not being set on the first command as it should.
This only affected the initial behavior of the "next" command without
mime support.
- Add the 'T' flag to many commands in cmdtab.c that should not look
like the first command. E.g., start mail on a mailbox with multiple
messages, run "set foo", then "next", and watch the second message get
displayed rather than the first as is the case without the first "set"
command.
- Add file descriptor and file handle leak detection. Enabled by
DEBUG_FILE_LEAK. This will likely disappear in the future.
- Fix a long standing (since import in 1993) longjmp() bug in
edstop(): the jmpbuf was invalid when quit() is called at the end of
main.
- Fix a long standing bug (since import in 1993) in snarf() where it
didn't strip whitespace correctly if the line consisted only of
whitespace.
- Lint cleanup.
- New Feature: "Header" command. This allows miscellaneous header
fields to be added to the header, e.g., "X-Organization:" or
"Reply-To:" fields.
- New Feature: "page-also" variable. This allows the specification of
additional commands to page. It is more flexible than "crt".
- Document the "pager-off" variable: if set, it disables paging
entirely.
