* net/wan/hdlc_ppp: use break in switchJesper Juhl2011-08-221-7/+7
| | | | | | | | | | | We'll either hit one of the case labels or the default in the switch and in all cases do we then 'goto out' and we also have a 'goto out' after the switch that is redundant. Change to just use break in the case statements and leave the 'goto out' after the lop for everyone to hit. Signed-off-by: Jesper Juhl <jj@chaosbits.net> Signed-off-by: David S.

* WAN: flush tx_queue in hdlc_ppp to prevent panic on rmmod hw_driver.Krzysztof Halasa2010-04-161-0/+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.

* syncppp: Fix crashes.David S. Miller2008-05-121-1/+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>

* [PATCH] Modularize generic HDLCKrzysztof Halasa2006-09-261-16/+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.

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!
