2005-09-14[PATCH] error path in setup_arg_pages() misses vm_unacct_memory()Hugh Dickins1-7/+2
Pavel Emelianov and Kirill Korotaev observe that fs and arch users of security_vm_enough_memory tend to forget to vm_unacct_memory when a failure occurs further down (typically in setup_arg_pages variants). These are all users of insert_vm_struct, and that reservation will only be unaccounted on exit if the vma is marked VM_ACCOUNT: which in some cases it is (hidden inside VM_STACK_FLAGS) and in some cases it isn't. So x86_64 32-bit and ppc64 vDSO ELFs have been leaking memory into Committed_AS each time they're run. But don't add VM_ACCOUNT to them, it's inappropriate to reserve against the very unlikely case that gdb be used to COW a vDSO page - we ought to do something about that in do_wp_page, but there are yet other inconsistencies to be resolved. The safe and economical way to fix this is to let insert_vm_struct do the security_vm_enough_memory check when it finds VM_ACCOUNT is set. And the MIPS irix_brk has been calling security_vm_enough_memory before calling do_brk which repeats it, doubly accounting and so also leaking. Remove that, and all the fs and arch calls to security_vm_enough_memory: give it a less misleading name later on.

2005-09-07[PATCH] compat: be more consistent about [ug]id_tStephen Rothwell1-8/+8
When I first wrote the compat layer patches, I was somewhat cavalier about the definition of compat_uid_t and compat_gid_t (or maybe I just misunderstood :-)). This patch makes the compat types much more consistent with the types we are being compatible with and hopefully will fix a few bugs along the way. compat type type in compat arch __compat_[ug]id_t __kernel_[ug]id_t __compat_[ug]id32_t __kernel_[ug]id32_t compat_[ug]id_t [ug]id_t The difference is that compat_uid_t is always 32 bits (for the archs we care about) but __compat_uid_t may be 16 bits on some.

2005-08-29[PATCH] convert signal handling of NODEFER to act like other Unix boxes.Steven Rostedt3-18/+15
It has been reported that the way Linux handles NODEFER for signals is not consistent with the way other Unix boxes handle it. I've written a program to test the behavior of how this flag affects signals and had several reports from people who ran this on various Unix boxes, confirming that Linux seems to be unique on the way this is handled. The way NODEFER affects signals on other Unix boxes is as follows: 1) If NODEFER is set, other signals in sa_mask are still blocked. 2) If NODEFER is set and the signal is in sa_mask, then the signal is still blocked. (Note: this is the behavior of all tested but Linux _and_ NetBSD 2.0 *). The way NODEFER affects signals on Linux: 1) If NODEFER is set, other signals are _not_ blocked regardless of sa_mask (Even NetBSD doesn't do this). 2) If NODEFER is set and the signal is in sa_mask, then the signal being handled is not blocked. The patch converts signal handling in all current Linux architectures to the way most Unix boxes work. Unix boxes that were tested: DU4, AIX 5.2, Irix 6.5, NetBSD 2.0, SFU 3.5 on WinXP, AIX 5.3, Mac OSX, and of course Linux 2.6.13-rcX. * NetBSD was the only other Unix to behave like Linux on point #2. The main concern was brought up by point #1 which even NetBSD isn't like Linux. So with this patch, we leave NetBSD as the lonely one that behaves differently here with #2.

machine_restart, machine_halt and machine_power_off are machine specific hooks deep into the reboot logic, that modules have no business messing with. Usually code should be calling kernel_restart, kernel_halt, kernel_power_off, or emergency_restart. So don't export machine_restart, machine_halt, and machine_power_off so we can catch buggy users.

2005-04-29[AUDIT] Don't allow ptrace to fool auditing, log arch of audited syscalls.1-10/+28
We were calling ptrace_notify() after auditing the syscall and arguments, but the debugger could have _changed_ them before the syscall was actually invoked. Reorder the calls to fix that. While we're touching ever call to audit_syscall_entry(), we also make it take an extra argument: the architecture of the syscall which was made, because some architectures allow more than one type of syscall. Also add an explicit success/failure flag to audit_syscall_exit(), for the benefit of architectures which return that in a condition register rather than only returning a single register. Change type of syscall return value to 'long' not 'int'. Signed-off-by: David Woodhouse <[email protected]>

2005-04-16Linux-2.6.12-rc2Linus Torvalds59-0/+22890
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
