[MIPS] Fix O32 personality(2) call with 0xffffffff argument.

2006-10-19T16:55:13+00:00

A sign extension bug did result in sys_personality being invoked with a
0xffffffffffffffffUL argument, so querying the current personality didn't
work.

[PATCH] VFS: Make filldir_t and struct kstat deal in 64-bit inode numbers

2006-10-03T15:03:40+00:00

These patches make the kernel pass 64-bit inode numbers internally when
communicating to userspace, even on a 32-bit system.  They are required
because some filesystems have intrinsic 64-bit inode numbers: NFS3+ and XFS
for example.  The 64-bit inode numbers are then propagated to userspace
automatically where the arch supports it.

Problems have been seen with userspace (eg: ld.so) using the 64-bit inode
number returned by stat64() or getdents64() to differentiate files, and
failing because the 64-bit inode number space was compressed to 32-bits, and
so overlaps occur.

This patch:

Make filldir_t take a 64-bit inode number and struct kstat carry a 64-bit
inode number so that 64-bit inode numbers can be passed back to userspace.

The stat functions then returns the full 64-bit inode number where
available and where possible.  If it is not possible to represent the inode
number supplied by the filesystem in the field provided by userspace, then
error EOVERFLOW will be issued.

Similarly, the getdents/readdir functions now pass the full 64-bit inode
number to userspace where possible, returning EOVERFLOW instead when a
directory entry is encountered that can't be properly represented.

Note that this means that some inodes will not be stat'able on a 32-bit
system with old libraries where they were before - but it does mean that
there will be no ambiguity over what a 32-bit inode number refers to.

Note similarly that directory scans may be cut short with an error on a
32-bit system with old libraries where the scan would work before for the
same reasons.

It is judged unlikely that this situation will occur because modern glibc
uses 64-bit capable versions of stat and getdents class functions
exclusively, and that older systems are unlikely to encounter
unrepresentable inode numbers anyway.

[PATCH] namespaces: utsname: switch to using uts namespaces

2006-10-02T14:57:21+00:00

Replace references to system_utsname to the per-process uts namespace
where appropriate.  This includes things like uname.

Changes: Per Eric Biederman's comments, use the per-process uts namespace
	for ELF_PLATFORM, sunrpc, and parts of net/ipv4/ipconfig.c

[PATCH] sysctl: Allow /proc/sys without sys_sysctl

2006-09-27T15:26:19+00:00

Since sys_sysctl is deprecated start allow it to be compiled out.  This
should catch any remaining user space code that cares, and paves the way
for further sysctl cleanups.

[PATCH] fix mips sys32_p{read,write}

2006-04-26T14:52:21+00:00

Switched to use of sys_pread64()/sys_pwrite64() rather than keep duplicating
their guts; among the little things that had been missing there were such as
	ret = security_file_permission (file, MAY_READ);
Gotta love the LSM robustness, right?

[PATCH] create struct compat_timex and use it everywhere

2006-03-26T16:56:57+00:00

We had a copy of the compatibility version of struct timex in each 64 bit
architecture.  This patch just creates a global one and replaces all the
usages of the old ones.
