the same order that option flags with a similar property are sorted.
This corresponds with the change made to the sort order of the short
names made in the previous update (1.4).
Right now, this change makes no difference at all, as there are no
long option names that differ only in char case (yet.)
are not harware streams audio_pint_silence is ineffective.
As audio_mix() was the only consumer of audio_pint_silence it has been
removed along with sc_sil_count - which was only used by this function.
One block of silence is also played in audio drivers using start_output
when draining the hardware, this helps playback of short (less than
blocksize) samples.
- when priming the pool and failing with ERESTART, don't decrement the number
of pages; this avoids the issue of returning an ERESTART when we get to 0,
and is more correct.
- simplify the pool_grow code, and don't wakeup things if we ENOMEM.
why we are doing that in the non-kaslr kernels, but let's just reproduce
the behavior.
jump_kernel is changed to use callq, so that the stack alignment is
preserved.
created sections are named .origname.i, for example:
.text -> { .text .text.0 .text.1 .text.2 .text.3 .text.4 }
Each section is randomized independently by the prekern - and in a random
order obviously. As a result we can get intertwined mappings, of the type:
+-------+-----------+------+---------+-----------+-------+-------+------+-
| text1 | NOTMAPPED | bss0 | rodata1 | NOTMAPPED | data2 | text3 | bss1 |
+-------+-----------+------+---------+-----------+-------+-------+------+-
---------+-
rodata0 | ...
---------+-
The CTF section is dropped completely, because (a) when split it becomes
enormous for some reason (that I don't quite understand, verily), and (b)
the kernel expects only one CTF and can't handle several of them.
segments, and rather map each section independently at a random VA.
In particular, .data and .bss are not merged anymore and reside at
different addresses.
resolved pathname. We need this in the case of scripts where p_path needs
to point to the interpreter and not the script itself. Otherwise things
like perl script that depend on /proc/$$/exe to re-exec themselves end up
being fork bombs.
In reality we should be using the fully resolved/canonicalized path here, but
namei is not giving it back to us.
segments anymore. Initially I did this because I wanted to compress the
sections by reducing the padding between them; but we'll handle that
differently.
