2020-07-24Merge branch 'get-rid-of-the-address_space-override-in-setsockopt-v2'David S. Miller87-742/+893
Christoph Hellwig says: ==================== get rid of the address_space override in setsockopt v2 setsockopt is the last place in architecture-independ code that still uses set_fs to force the uaccess routines to operate on kernel pointers. This series adds a new sockptr_t type that can contained either a kernel or user pointer, and which has accessors that do the right thing, and then uses it for setsockopt, starting by refactoring some low-level helpers and moving them over to it before finally doing the main setsockopt method. Note that apparently the eBPF selftests do not even cover this path, so the series has been tested with a testing patch that always copies the data first and passes a kernel pointer. This is something that works for most common sockopts (and is something that the ePBF support relies on), but unfortunately in various corner cases we either don't use the passed in length, or in one case actually copy data back from setsockopt, or in case of bpfilter straight out do not work with kernel pointers at all. Against net-next/master. Changes since v1: - check that users don't pass in kernel addresses - more bpfilter cleanups - cosmetic mptcp tweak ==================== Signed-off-by: David S.

2020-07-24net: optimize the sockptr_t for unified kernel/user address spacesChristoph Hellwig3-9/+43
For architectures like x86 and arm64 we don't need the separate bit to indicate that a pointer is a kernel pointer as the address spaces are unified. That way the sockptr_t can be reduced to a union of two pointers, which leads to nicer calling conventions. The only caveat is that we need to check that users don't pass in kernel address and thus gain access to kernel memory. Thus the USER_SOCKPTR helper is replaced with a init_user_sockptr function that does this check and returns an error if it fails.

2020-07-24Merge branch 'TC-datapath-hash-api'David S. Miller5-0/+49
Ariel Levkovich says: ==================== TC datapath hash api Hash based packet classification allows user to set up rules that provide load balancing of traffic across multiple vports and for ECMP path selection while keeping the number of rule at minimum. Instead of matching on exact flow spec, which requires a rule per flow, user can define rules based on a their hash value and distribute the flows to different buckets. The number of rules in this case will be constant and equal to the number of buckets. The series introduces an extention to the cls flower classifier and allows user to add rules that match on the hash value that is stored in skb->hash while assuming the value was set prior to the classification. Setting the skb->hash can be done in various ways and is not defined in this series - for example: 1. By the device driver upon processing an rx packet. 2. Using tc action bpf with a program which computes and sets the skb->hash value. $ tc filter add dev ens1f0_0 ingress \ prio 1 chain 2 proto ip \ flower hash 0x0/0xf \ action mirred egress redirect dev ens1f0_1 $ tc filter add dev ens1f0_0 ingress \ prio 1 chain 2 proto ip \ flower hash 0x1/0xf \ action mirred egress redirect dev ens1f0_2 v3 -> v4: *Drop hash setting code leaving only the classidication parts. Setting the hash will be possible via existing tc action bpf. v2 -> v3: *Split hash algorithm option into 2 different actions. Asym_l4 available via act_skbedit and bpf via new act_hash. ==================== Signed-off-by: David S. Miller <[email protected]>
