2010-04-16WAN: flush tx_queue in hdlc_ppp to prevent panic on rmmod hw_driver.Krzysztof Halasa1-0/+6
tx_queue is used as a temporary queue when not allowed to queue skb directly to the hw device driver (which may sleep). Most paths flush it before returning, but ppp_start() currently cannot. Make sure we don't leave skbs pointing to a non-existent device. Thanks to Michael Barkowski for reporting this problem. Signed-off-by: Krzysztof Hałasa <khc@pm.waw.pl> Signed-off-by: David S.

2009-09-11drivers/net/wan: introduce missing kfreeJulia Lawall1-0/+1
Error handling code following a kmalloc should free the allocated data. The semantic match that finds the problem is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @r exists@ local idexpression x; statement S; expression E; identifier f,f1,l; position p1,p2; expression *ptr != NULL; @@ x@p1 = \(kmalloc\|kzalloc\|kcalloc\)(...); ... if (x == NULL) S <... when != x when != if (...) { <+...x...+> } ( x->f1 = E | (x->f1 == NULL || ...) | f(...,x->f1,...) ) ...> ( return \(0\|<+...x...+>\|ptr\); | return@p2 ...; ) @script:python@ p1 << r.p1; p2 << r.p2; @@ print "* file: %s kmalloc %s return %s" % (p1[0].file,p1[0].line,p2[0].line) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: David S.

2008-05-12syncppp: Fix crashes.David S. Miller1-1/+1
The syncppp layer wants a mid-level netdev private pointer. It was using netdev->priv but that only worked by accident, and thus this scheme was broken when the device private allocation strategy changed. Add a proper mid-layer private pointer for uses like this, update syncppp and all users, and remove the HDLC_PPP broken tag from drivers/net/wan/Kconfig Signed-off-by: David S. Miller <davem@davemloft.net>

2006-09-26[PATCH] Modularize generic HDLCKrzysztof Halasa1-16/+61
This patch enables building of individual WAN protocol support routines (parts of generic HDLC) as separate modules. All protocol-private definitions are moved from hdlc.h file to protocol drivers. User-space interface and interface between generic HDLC and underlying low-level HDLC drivers are unchanged.

2005-04-16Linux-2.6.12-rc2Linus Torvalds1-0/+115
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
