[DCCP]: Allocation in atomic context

2007-08-22T03:58:06+00:00

This fixes the following bug reported in syslog:

[DCCP]: fix memory leak and clean up style - dccp_feat_empty_confirm()

2007-08-14T05:52:10+00:00

There's a memory leak in net/dccp/feat.c::dccp_feat_empty_confirm().  If we
hit the 'default:' case of the 'switch' statement, then we return without
freeing 'opt', thus leaking 'struct dccp_opt_pend' bytes.

The leak is fixed easily enough by adding a kfree(opt); before the return
statement.

The patch also changes the layout of the 'switch' to be more in line with
CodingStyle.

[DCCP]: fix theoretical ccids_{read,write}_lock() race

2007-08-14T05:52:09+00:00

Make sure that spin_unlock_wait() is properly ordered wrt atomic_inc().

(akpm: can't we convert this code to use rwlocks?)

mm: Remove slab destructors from kmem_cache_create().

2007-07-20T01:11:58+00:00

Slab destructors were no longer supported after Christoph's
c59def9f222d44bb7e2f0a559f2906191a0862d7 change. They've been
BUGs for both slab and slub, and slob never supported them
either.

This rips out support for the dtor pointer from kmem_cache_create()
completely and fixes up every single callsite in the kernel (there were
about 224, not including the slab allocator definitions themselves,
or the documentation references).

jprobes: remove JPROBE_ENTRY()

2007-07-19T17:04:44+00:00

AFAICT now that jprobe.entry is a void *, JPROBE_ENTRY doesn't do anything
useful - so remove it ..

I've left a do-nothing version so that out-of-tree jprobes code will still
compile without modifications.

[CCID3]: Fix a bug in the send time processing

2007-07-11T05:15:34+00:00

ccid3_hc_tx_send_packet currently returns 0 when the time difference between
current time and t_nom is less than 1000 microseconds.

In this case the packet is sent immediately; but, unlike other packets that can
be emitted on first attempt, it will not have its window counter updated and
its options set as required. This is a bug.

Fix: Require the time difference to be at least 1000 microseconds. The
algorithm then converges: time differences > 1000 microseconds trigger the
timer in dccp_write_xmit; after timer expiry this function is tried again; when
the time difference is less than 1000, the packet will have its options added
and window counter updated as required.
