supported options can't get out of sync. This add support for the
linux __WCLONE and __WALL options (NetBSD version: WALTSIG and WALLSIG)
Add a diagnostic check to see if the one unhandled option (__WNOTHREAD) is
specified.
This should prevent linux processes from losing their children and creating
tons of zombie processes.
segment should succeed even if the segment would be marked removed; use this
to implement the Linux-compatible semantics of shmat(2)
this fixes the old Linux VMware3 graphics problem with local display,
and possibly other local Linux X clients using MIT-SHM
for Linux-compatible shmat() behaviour - shmat() for the removed shared memory
segment must work from all callers, the shared memory id could be passed e.g.
to native X server via MIT-SHM
temporarily remove the functionality, the Linux-compatible semantics
will be reimplemented differently
provide f_frsize. It cannot be actually used to GNU C statvfs() bug
in f_frsize != f_bsize case, so just keep pretending we don't support it.
Update comments and explain the situation in detail there.
explicit size types - the structure definition is actually identical
on currently support COMPAT_LINUX archs, so no point to have 6 copies of it
in the tree
- filesystem size is expressed in number of fragments, not blocks;
this fixes computed filesystem sizes for Linux df(1) and other Linux
binaries using statfs(2) for filesystems, which use different value
for frament and block, such as FFS
- use FS f_namemax instead of always using MAXNAMLEN
- print the socketcall type
- special case socket(2) call, it's also the only one with first argument
not being a socket descriptor
- only dump the relevant part of linux_socketcall_dummy_args, instead
of always the whole structure
grow-down auto extend segment) by allocating segment sized at
current stack size limit, and offsetting requested/returned address
as required
due to how normal virtual memory management work, allocating the
full sized stack memory segment up-front actually requires exactly same
amount of VA space and physical memory as the Linux 'grow' scheme and the
'grow' scheme is quite a lot more difficult to use in applications correctly,
so it's not very apparent why Linux introduced this feature at all
this fixes Thomas Klausner's Heroes3 crash, and might also
fix PR 26687 by Jan Schaumann
rather than EPERM; to emulate this properly, translate the error to EISDIR
if the target patch exists and points to a directory
this fixes the 'ant clean' problem reported by Marc Recht on current-users@
with SuSE 9.1 libraries
share same 'break' value used for brk()/sbrk(), otherwise application SIGSEGVs
quickly once different threads try to adjust data segment size
this fixes linux Mozilla crashes with SuSE 9.1 libraries, and possibly
other linux applications using real threads
connect madvise(2) and mincore(2) - apparently the newer Linux libs
don't stub it anymore, so allow the application to take advantage
of them
the Linux calls appear to be compatible in the flag values and semantics,
so a wrapper is not necessary
