- Update main file from 5.1 to 5.1.8 (includes patches 1 to 8)
- Remove patches 1 to 4
- Changelog - Patches 1 to 4 from the previous IPFire version together with patches 5 to
8 are now included into bash-5.1.8 followed by application of patches 9 to 12
Patch 12
There is a possible race condition that arises when a child process receives
a signal trapped by the parent before it can reset the signal dispositions.
The child process is not supposed to trap the signal in this circumstance.
Patch 11
When reading a compound assignment, and running it through the parser to
split it into words, we need to save and restore any alias we're currently
expanding.
Patch 10
If `wait -n' is interrupted by a trapped signal other than SIGINT, it does
not completely clean up state, and that can prevent subsequent calls to
`wait -n' from working correctly.
Patch 9
The bash malloc implementation of malloc_usable_size() does not follow the
specification. This can cause library functions that use it to overwrite
memory bounds checking.
Patch 8
Process substitution FIFOs opened by child processes as targets of redirections
were not removed appropriately, leaving remnants in the file system.
Patch 7
The code to check readline versions in an inputrc file had the sense of the
comparisons reversed.
Patch 6
Make sure child processes forked to run command substitutions are in the
proper process group.
Patch 5
Fix two memory leaks when assigning arrays using compound assignment syntax.
