[PATCH] vrf: Do not attempt to create IPv6 mcast rule if IPv6 is disabled
by Yang Yingliang 16 Jan '20

16 Jan '20

From: David Ahern <dsahern(a)gmail.com> mainline inclusion from mainline-v5.4-rc1 commit dac91170f8e9c73784af5fad6225e954b795601c category: bugfix bugzilla: 23512 CVE: NA ------------------------------------- A user reported that vrf create fails when IPv6 is disabled at boot using 'ipv6.disable=1': https://bugzilla.kernel.org/show_bug.cgi?id=204903 The failure is adding fib rules at create time. Add RTNL_FAMILY_IP6MR to the check in vrf_fib_rule if ipv6_mod_enabled is disabled.

[PATCH] ext4: check for directory entries too close to block end
by Yang Yingliang 16 Jan '20

16 Jan '20

From: Jan Kara <jack(a)suse.cz> commit 109ba779d6cca2d519c5dd624a3276d03e21948e upstream. ext4_check_dir_entry() currently does not catch a case when a directory entry ends so close to the block end that the header of the next directory entry would not fit in the remaining space. This can lead to directory iteration code trying to access address beyond end of current buffer head leading to oops.

[PATCH] ext4: fix ext4_empty_dir() for directories with holes
by Yang Yingliang 16 Jan '20

16 Jan '20

From: Jan Kara <jack(a)suse.cz> commit 64d4ce892383b2ad6d782e080d25502f91bf2a38 upstream. Function ext4_empty_dir() doesn't correctly handle directories with holes and crashes on bh->b_data dereference when bh is NULL. Reorganize the loop to use 'offset' variable all the times instead of comparing pointers to current direntry with bh->b_data pointer. Also add more strict checking of '.' and '..' directory entries to avoid entering loop in possibly invalid state on corrupted filesystems.

Good Day Where should I ask about the hardware set planned for first development support? I have a trash netbook based on ATM7029 is a good candidate in case anybody can find SDK for this SoC. https://aliexpress.ru/item/32891360597.html ------------------------------ With best regards, Dmitry Ponyatov, IoT/embedded engineer, tel. +7 917 10 10 818
