[make-initrd] [PATCH v2 00/11] Improve support for atomic actions

[Alexey Gladkov <gladkov.alexey@gmail.com>]

Нашлось ещё ряд мест, где потенциально могут возникнуть проблемы из-за
параллельного доступа к файлам на чтение/запись.

Я добавил новый API не только для flock-блокировок, но и для более атомарного
обновления файлов.

Вроде исправил всё что нашёл.


Alexey Gladkov (10):
  runtime: Fix console lock shadowing by /dev mount
  runtime: Avoid leaking lock descriptor 90 to child processes
  runtime: Replace /.initrd/initenv locking with atomic file update
  runtime: Centralize file and console locking helpers
  create-rootfs: Require bash 4.1 or newer for initramfs
  network: Share DHCP hook lock between IPv4 and IPv6 on the same
    interface
  luks: Serialize /etc/luks.keys updates and avoid duplicate entries
  runtime: Synchronize concurrent /etc/fstab access with shared and
    exclusive locks
  runtime: Update rootdelay deadline and failure message atomically
  runtime: Centralize atomic file replacement in write_atomic helper

Egor Shestakov (1):
  runtime: Fix a lock leak in rootdelayd
