Some of the changes in balloc.c are just cosmetic, as Andreas pointed out - if they overflow they'll then underflow and things are fine. 5th hunk actually fixes an overflow problem. Also check for potential overflows in inode & block counts when resizing. Signed-off-by:

SWsoft Virtuozzo/OpenVZ Linux kernel team has discovered that ext3 error behavior was broken in linux kernels since 2.5.x versions by the following patch: 2002/10/31 02:15:26-05:00 tytso@snap.thunk.org Default mount options from superblock for ext2/3 filesystems http://linux.bkbits.net:8080/linux-2.6/gnupatch@3dc0d88eKbV9ivV4ptRNM8fBuA3JBQ In case ext3 file system is mounted with errors=continue (EXT3_ERRORS_CONTINUE) errors should be ignored when possible. However at present in case of any error kernel aborts journal and remounts filesystem to read-only. Such behavior was hit number of times and noted to differ from that of 2.4.x kernels. This patch fixes this: - do nothing in case of EXT3_ERRORS_CONTINUE, - set EXT3_MOUNT_ABORT and call journal_abort() in all other cases - panic() should be called after ext3_commit_super() to save sb marked as EXT3_ERROR_FS Signed-off-by:

In the past there were a few kernel panics related to block reservation tree operations failure (insert/remove etc). It would be very useful to get the block allocation reservation map info when such error happens. Signed-off-by:

These are a few places I've found in jbd that look like they may not be 16T-safe, or consistent with the use of unsigned longs for block containers. Problems here would be somewhat hard to hit, would require journal blocks past the 8T boundary, which would not be terribly common. Still, should fix. (some of these have come from the ext4 work on jbd as well). I think there's one more possibility that the wrap() function may not be safe IF your last block in the journal butts right up against the 232 block boundary, but that seems like a VERY remote possibility, and I'm not worrying about it at this point.

This is primarily format string fixes, with changes to ialloc.c where large inode counts could overflow, and also pass around journal_inum as an unsigned long, just to be pedantic about it.... Signed-off-by:

I need to do some actual IO testing now, but this gets things mounting for a 16T ext3 filesystem. (patched up e2fsprogs is needed too, I'll send that off the kernel list) This patch fixes these issues in the kernel: o sbi->s_groups_count overflows in ext3_fill_super() sbi->s_groups_count = (le32_to_cpu(es->s_blocks_count) - le32_to_cpu(es->s_first_data_block) + EXT3_BLOCKS_PER_GROUP(sb) - 1) / EXT3_BLOCKS_PER_GROUP(sb); at 16T, s_blocks_count is already maxed out; adding EXT3_BLOCKS_PER_GROUP(sb) overflows it and groups_count comes out to 0. Not really what we want, and causes a failed mount. Feel free to check my math (actually, please do!), but changing it this way should work & avoid the overflow: (A + B - 1)/B changed to: ((A - 1)/B) + 1 o ext3_check_descriptors() overflows range checks ext3_check_descriptors() iterates over all block groups making sure that various bits are within the right block ranges... on the last pass through, it is checking the error case [item] >= block + EXT3_BLOCKS_PER_GROUP(sb) where "block" is the first block in the last block group. The last block in this group (and the last one that will fit in 32 bits) is block + EXT3_BLOCKS_PER_GROUP(sb)- 1. block + EXT3_BLOCKS_PER_GROUP(sb) wraps back around to 0. so, make things clearer with "first_block" and "last_block" where those are first and last, inclusive, and use <, > rather than <, >=. Finally, the last block group may be smaller than the rest, so account for this on the last pass through: last_block = sb->s_blocks_count - 1; (a similar patch could be done for ext2; does anyone in their right mind use ext2 at 16T? I'll send an ext2 patch doing the same thing if that's warranted) Signed-off-by:

There's no point to rewrite some logic to parse command line to pass initrd parameters or to declare a user memory area. We could use instead parse_early_param() that does the same thing. Signed-off-by:

This function although doing simple thing is hard to follow. It's mainly due to: - a lot of #ifdef - bad local names - redundant tests So this patch try to address these issues. It also do not use max_pfn global which is marked as an unused exported symbol. As a bonus side, it's now really easy to see what part of the code is for no-numa system. There's also no point to make this function inline. Signed-off-by: -

This array was used to 'cache' some frame info about scheduler functions to speed up get_wchan(). This array was 1Ko size and was only used when CONFIG_KALLSYMS was set but declared for all configs. Rather than make the array statement conditional, this patches removes this array and its uses. Indeed the common case doesn't seem to use this array and get_wchan() is not a critical path anyways. It results in a smaller bss and a smaller/cleaner code: text data bss dec hex filename 2543808 254148 139296 2937252 2cd1a4 vmlinux-new-get-wchan 2544080 254148 143392 2941620 2ce2b4 vmlinux~old Signed-off-by:

This patch adds 2 sanity checks. The first one test that the start address of the function to analyze has been set by the caller. If not return an error since nothing usefull can be done without. The second one checks that the function's size has been set. A null size can happen if CONFIG_KALLSYMS is not set and it means that we don't know the size of the function to analyze. In this case, we make it equal to 128 instructions by default. Signed-off-by:

MIPS is the only port to call its fstatat()-related syscalls "__NR_fstatat". Now I can see why that might be seen as every other port being wrong, but I think for o32, it is at best confusing. __NR_fstat provides a plain (32-bit) stat while __NR_fstatat provides a 64-bit stat. Changing the name to __NR_fstatat64 would make things more explicit, match x86, and make the glibc port slightly easier. The current name is more appropriate for n32 and n64, but it would be appropriate for other 64-bit targets too, and those targets have chosen to call it __NR_newfstatat instead. Using the same name for MIPS would again be more consistent and make the glibc port slightly easier. I'm not wedded to this idea if the current names are preferred, but FWIW... Signed-off-by:

While working on a glibc patch to support the fstatat() functions[1], I noticed that the o32 implementation behaves differently on 32-bit and 64-bit kernels; the former provides a stat64 while the latter provides a plain (o32) stat. I think the former is what's intended, as there is no separate fstatat64. It's also what x86 does. I think this is just a case of a compat too far. [1] I've seen Khem's patch, but I don't think it's right. Signed-off-by:

The code in pgtable-64.h assumes TASK_SIZE is always bigger than a first level PGDIR_SIZE. This is not the case for 64K pages, where task size is 40 bits (1TB) and a pgd entry can map 42 bits. This leads to USER_PTRS_PER_PGD being zero for 64K pages. Signed-off-by:

thomas@koeller.dyndns.org authored
The excite platform exports hardware resources for device drivers to use. Any driver wanting to use these resources will look up them by their names. Since these resources are declared to have static linkage, but are not used in the source file defining them, the compiler used to emit an 'unused' warning, which this patch suppresses.
