[PATCH openEuler-1.0-LTS 1/2] ext4: fix bug in extents parsing when eh_entries == 0 and eh_depth > 0
by Yongqiang Liu 26 Nov '22

26 Nov '22

From: Luís Henriques <lhenriques(a)suse.de> mainline inclusion from mainline-v6.0-rc7 commit 29a5b8a137ac8eb410cc823653a29ac0e7b7e1b0 category: bugfix bugzilla: 187444, https://gitee.com/openeuler/kernel/issues/I6261Z CVE: NA -------------------------------- When walking through an inode extents, the ext4_ext_binsearch_idx() function assumes that the extent header has been previously validated. However, there are no checks that verify that the number of entries (eh->eh_entries) is non-zero when depth is > 0. And this will lead to problems because the EXT_FIRST_INDEX() and EXT_LAST_INDEX() will return garbage and result in this: [ 135.245946] ------------[ cut here ]------------ [ 135.247579] kernel BUG at fs/ext4/extents.c:2258!

[PATCH OLK-5.10 v4] mm: Fix kabi change caused by saved_auxv[] in mm_struct for x86_64
by Zheng Zengkai 23 Nov '22

openeuler inclusion category: bugfix bugzilla: https://gitee.com/openeuler/intel-kernel/issues/I5RQLJ CVE: NA Intel-SIG: mm: Fix kabi change caused by saved_auxv[] in mm_struct for x86_64. -------------------------------- Use the KABI_DEPRECATE and KABI_USE macro to fix kabi change caused by commit 1c33bb050750 ("x86/elf: Support a new ELF aux vector AT_MINSIGSTKSZ"). The extended saved_auxv[] causes the kabi breakage, move the saved_auxv[] to the end of struct mm_struct. To avoid introducing too many size increase of mm_struct, use a pointer to indirectly reference the relocated saved_auxv[], then adapt the code where mm->saved_auxv is used.
