Hi Keir: [NET] front: Fix features on resume when csum is off When the netfront driver is resumed the features are renegotiated with the backend. However, I forgot take into account the status of the TX checksum setting. When TX checksum is disabled by the user, we cannot enable SG or TSO since both require checksum offload. This patch makes xennet check the checksum setting before

Hi: The following patch replaces a bash-specific substitution with equivalent POSIX /bin/sh substitutions. This allows a Xen-patched Linux to build when /bin/sh is a POSIX shell other than bash.

Hi: I noticed a bug in the realloc error checking code in the QEMU backend for RealTek8139. However, what''s worse is that there is no cap on the total size of the transmit buffer at all. So a guest can keep extending it until memory runs out. CP_TX_BUFFER_SIZE is already 64K. So it seems to me that we don''t need the while loop to extend the buffer at all since no transmitted

Hi: Here are the patches I used for testing KVM with virtio-net using TSO. There are three patches for the tun device which are basically Rusty's patches with the mmap turned into copying (for correctness). Two patches are for the virtio-net frontend, one required to support receiving SG/TSO, and the other useful for testing SG per se. The other patch is to the KVM backend to make all this

Hi Keir: These two patches remove the need for netloop by performing the copying in netback and only if it is necessary. The rationale is that most packets will be processed without delay allowing them to be freed without copying at all. So instead of copying every packet destined to dom0 we''ll only copy those that linger longer than a specified amount of time (currently 0.5s). As it

Hi Herbert, I wonder if you''ve got a chance to look at netfront in light of the new stuff in davem''s network tree (the stuff that''s in http://git.kernel.org/?p=linux/kernel/git/davem/net-2.6.22.git). In particular, struct sk_buff has been changed so that "nh" has gone, and the replacement can be just an offset rather than a full pointer. This breaks the

Hello! The rcu_assign_pointer() primitive currently unconditionally executes a memory barrier, even when a NULL pointer is being assigned. This has lead some to avoid using rcu_assign_pointer() for NULL pointers, which loses the self-documenting advantages of rcu_assign_pointer() This patch uses __builtin_const_p() to omit needless memory barriers for NULL-pointer assignments at compile time

Peter, i ask you to permit discussion of `dash' in the klibc list. Pulled reasons are, that bugs and followups are distributed in bug tracking systems with arbitrary decisions. In the klibc there are also changes, that can be discussed widely, and opinions with possible solutions published. So far i have two problems. First is proposed change for test(1):

Greetings all, I've setup a new gretap device as per Herbert Xu's new patches and it works as expected for smaller MTU. I'm wondering if gretap tunnels handle fragmentation at all or if this might be a bridge related issue. The same setup works quite well if I use vtun with a tap device however, so while this isn't entirely bridge-related, Maybe someone here might have

patch is also available in current patch queue: git pull git://git.debian.org/users/maks/klibc.git maks Run it on latest dash and it could still test readable files as readable.
