Binfmt_flat: Add minimum support for the Blackfin relocations

2007-10-03T15:41:43+00:00

Add minimum support for the Blackfin relocations, since we don't have
enough space in each reloc.  The idea is to store a value with one
relocation so that subsequent ones can access it.

Actually, this patch is required for Blackfin.  Currently if BINFMT_FLAT is
enabled, git-tree kernel will fail to compile.

[PATCH] uclinux: correctly remap bin_fmtflat exe allocated mem regions

2007-02-09T18:45:33+00:00

remap() the region we get from mmap() to mark the fact that we are
using all of the available slack space. Any slack space is used
to form a simple brk region, and potentially more stack space than
requested at load time.

Any searches of the vma chain may well fail looking for
stack (and especially arg) addresses if the remaping is not done.
The simplest example is /proc//cmdline, since the args
are pretty much always at the top of the data/bss/stack region.

[PATCH] VFS: change struct file to use struct path

2006-12-08T16:28:41+00:00

This patch changes struct file to use struct path instead of having
independent pointers to struct dentry and struct vfsmount, and converts all
users of f_{dentry,vfsmnt} in fs/ to use f_path.{dentry,mnt}.

Additionally, it adds two #define's to make the transition easier for users of
the f_dentry and f_vfsmnt.

[PATCH] uclinux: use PER_LINUX_32BIT in binfmt_flat

2006-06-26T04:04:24+00:00

binfmt_flat.c calls set_personality with PER_LINUX as the personality.
On the arm architecture this results in the program running in 26bit
usermode.  PER_LINUX_32BIT should be used instead.  This doesn't affect
other architectures that use binfmt_flat.

[PATCH] binfmt_flat: don't check for EMFILE

2006-05-21T19:59:17+00:00

Bernd Schmidt points out that binfmt_flat is now leaving the exec file open
while the application runs.  This offsets all the application's fd numbers.
We should have closed the file within exec(), not at exit()-time.

But there doesn't seem to be a lot of point in doing all this just to avoid
going over RLIMIT_NOFILE by one fd for a few microseconds.  So take the EMFILE
checking out again.  This will cause binfmt_flat to again fail LTP's
exec-should-return-EMFILE-when-fdtable-is-full test.  That test appears to be
wrong anyway - Open Group specs say nothing about exec() returning EMFILE.

[PATCH] flat binary loader doesn't check fd table full

2006-03-25T16:23:01+00:00

In binfmt_flat.c, the flat binary loader should check file descriptor table
and install the fd on the file.

Convert the function to single-exit and fix this bug.

[PATCH] uclinux: delay binfmt_flat trace

2006-01-10T17:31:27+00:00

Modify the initial trace output (which is based on flags in the binary
header) so that it is not done until after the magic number check.  This
may well not be a flat format binary, so the flags could be invalid.
(Prime example, running a script).

Changes prompted by patches from Stuart Hughs.
