ChangeSet@1.1866, 2004-07-23 22:18:59-07:00, anton@samba.org [PATCH] Fix ppc64 max_pfn issue I noticed excessive time in the pid hash functions on a ppc64 box. It turns out the pid hash is being sized way too small, eg on a 16GB box: PID hash table entries: 16 (order 4: 256 bytes) The reason is that the pid hash init function uses max_pfn before it was setup on ppc64. With the following patch things are good again: PID hash table entries: 4096 (order 12: 65536 bytes) Signed-off-by: Anton Blanchard Signed-off-by: Linus Torvalds ChangeSet@1.1865, 2004-07-23 10:26:36-07:00, davidm@napali.hpl.hp.com [PATCH] NX: allow architectures to select legacy mode dynamically On some platforms, you'll want to support READ_IMPLIES_EXEC differently depending on personality (e.g, native binary vs. x86 binary). This supports that (and makes the code more readable while at it) by replacing the old architecture-specific fixed LEGACY_BINARIES macro define with a architecture-specific "elf_read_implies_exec_binary()" helper function. For now, x86 is the only user, and sets the "read implies exec" bit for legacy apps. ia64 and x86-64 are likely to want to do their own thing. Acked by Ingo.

It creates an enum of the four code-points defined by RFC3168 and uses them throughout the inet_ecn.h file. The only non-trivial bit is in IP_ECN_set_ce/IP6_ECN_set_ce where the patch uses INET_ECN_CE instead of 1. This is OK as those functions assume that the ECT bit is already set.

The stack allocation in crypt() is bogus as whether tmp_src/tmp_dst is used is determined by factors unrelated to nbytes and src->length/dst->length. Since the condition for whether tmp_src/tmp_dst are used is very complex, let's allocate them always instead of guessing.

If this bit is set then PROT_READ will also add the PROT_EXEC bit - as expected by legacy x86 binaries. The ELF loader will automatically set this bit when it encounters a legacy binary. This approach avoids the problems the previous ->def_flags solution caused. In particular this patch fixes the PROT_NONE problem in a cleaner way (http://lkml.org/lkml/2004/7/12/227), and it should fix the ia64 PROT_EXEC problem reported by David Mosberger. Also, mprotect(PROT_READ) done by legacy binaries will do the right thing as well. the details: - the personality bit is added to the personality mask upon exec(), within the ELF loader, but is not cleared (see the exceptions below). This means that if an environment that already has the bit exec()s a new-style binary it will still get the old behavior. - one exception are setuid/setgid binaries: these will reset the bit - thus local attackers cannot manually set the bit and circumvent NX protection. Legacy setuid binaries will still get the bit through the ELF loader. This gives us maximum flexibility in shaping compatibility environments. - selinux also clears the bit when switching SIDs via exec(). - x86 is the only arch making use of READ_IMPLIES_EXEC currently. Other arches will have the pre-NX-patch protection setup they always had. I have booted an old distro [RH 7.2] and two new PT_GNU_STACK distros [SuSE 9.2 and FC2] on an NX-capable CPU - they work just fine and all the mapping details are right. I've checked the PROT_NONE test-utility as well and it works as expected. I have checked various setuid scenarios as well involving legacy and new-style binaries. an improved setarch utility can be used to set the personality bit manually: http://redhat.com/~mingo/nx-patches/setarch-1.4-3.tar.gz the new '-X' flag does it, e.g.: ./setarch -X linux /bin/cat /proc/self/maps will trigger the old protection layout even on a new distro.

When you have two serial drivers, (e.g. 8250 and PMAC_ZILOG) they both say "I want to reserve X ports starting with major TTY_MAJOR and minor 64". By the time pmac_zilog gets there, the ports it requests are already reserved. Unfortunately, init_pmz() doesn't check for pmz_register() failure, and so it merrily goes on to register the half-initialized pmac_zilog driver with the power management subsystem. This path provides a proper failure path. Also: Restore ppc configs now that I know people use AT Keyboards on CHRP and PReP machines, and the zilog driver is no longer Oops'ing.
