__RASSERT format string does not use the PID argument. reiserfs_panic arguments are therefore formatted with the wrong format specifier (for example __LINE__ with %s). This bug was introduced when commit c3a9c210 ("reiserfs: rework reiserfs_panic") removed a "reiserfs[%i]" prefix. This bug is only triggered when using CONFIG_REISERFS_CHECK, otherwise __RASSERT is never used.

Currently quota format that supports 64-bit usage sets maximum quota limit as 2^64-1. However quota core code uses signed numbers to track usage and even limits themselves are stored in long long. Checking of maximum allowable limits worked by luck until commit 14bf61ff (quota: Switch ->get_dqblk() and ->set_dqblk() to use bytes as space units) because variable we compared with was unsigned. After that commit the type we compared against changed to signed and thus checks for maximum limits with the newest VFS quota format started to refuse any non-negative value. Later the problem was inadvertedly fixed by commit b10a0819 (quota: Store maximum space limit in bytes) because we started to compare against unsigned type as well. Fix possible future problems of this kind by setting maximum limits to 2^63-1 to avoid overflow issues. Reported-by: Carlos Carvalho <carlos@fisica.ufpr.br> Signed-off-by: Jan Kara <jack@suse.cz>

Setting timers or warning counts for id 0 via Q_XSETQLIM is used to actually set time limits and warning limits for all users. Hook up ->set_info to this so that VFS quota time limits get set the same way as XFS ones. When doing this Q_XSETQLIM for XFS is effectively split into two independent transactions - one for setting timers and warning limits and one for setting space and inode limits. Although this is inefficient, it is rare enough that it does not matter. Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jan Kara <jack@suse.cz>

The "usual" path is: - rt_mutex_slowlock() - set_current_state() - task_blocks_on_rt_mutex() (ret 0) - __rt_mutex_slowlock() - sleep or not but do return with __set_current_state(TASK_RUNNING) - back to caller. In the early error case where task_blocks_on_rt_mutex() return -EDEADLK we never change the task's state back to RUNNING. I assume this is intended. Without this change after ww_mutex using rt_mutex the selftest passes but later I get plenty of: | bad: scheduling from the idle thread! backtraces.

Core mm expects __PAGETABLE_{PUD,PMD}_FOLDED to be defined if these page table levels folded. Usually, these defines are provided by <asm-generic/pgtable-nopmd.h> and <asm-generic/pgtable-nopud.h>. But some architectures fold page table levels in a custom way. They need to define these macros themself. This patch adds missing defines. The patch fixes mm->nr_pmds underflow and eliminates dead __pmd_alloc() and __pud_alloc() on architectures without these page table levels. Signed-off-by: Kirill A.

Historically, !__GFP_FS allocations were not allowed to invoke the OOM killer once reclaim had failed, but nevertheless kept looping in the allocator. Commit 9879de73 ("mm: page_alloc: embed OOM killing naturally into allocation slowpath"), which should have been a simple cleanup patch, accidentally changed the behavior to aborting the allocation at that point. This creates problems with filesystem callers (?) that currently rely on the allocator waiting for other tasks to intervene.

Each inode of nilfs2 stores a root node of a b-tree, and it turned out to have a memory overrun issue: Each b-tree node of nilfs2 stores a set of key-value pairs and the number of them (in "bn_nchildren" member of nilfs_btree_node struct), as well as a few other "bn_*" members. Since the value of "bn_nchildren" is used for operations on the key-values within the b-tree node, it can cause memory access overrun if a large number is incorrectly set to "bn_nchildren". For instance, nilfs_btree_node_lookup() function determines the range of binary search with it, and too large "bn_nchildren" leads nilfs_btree_node_get_key() in that function to overrun. As for intermediate b-tree nodes, this is prevented by a sanity check performed when each node is read from a drive, however, no sanity check has been done for root nodes stored in inodes. This patch fixes the issue by adding missing sanity check against b-tree root nodes so that it's called when on-memory inodes are read from ifile, inode metadata file.
