2021-02-15net: broadcom: bcm4908_enet: set MTU on open & on requestRafał Miłecki
Hardware comes up with default max frame size set to 1518. When using it with switch it results in actual Ethernet MTU 1492: 1518 - 14 (Ethernet header) - 4 (Broadcom's tag) - 4 (802.1q) - 4 (FCS) Above means hardware in its default state can't handle standard Ethernet traffic (MTU 1500). Define maximum possible Ethernet overhead and always set MAC max frame length accordingly. This change fixes handling Ethernet frames of length 1506 - 1514.

2021-02-15bpf: Clear subreg_def for global function return valuesIlya Leoshkevich
test_global_func4 fails on s390 as reported by Yauheni in [1]. The immediate problem is that the zext code includes the instruction, whose result needs to be zero-extended, into the zero-extension patchlet, and if this instruction happens to be a branch, then its delta is not adjusted. As a result, the verifier rejects the program later. However, according to [2], as far as the verifier's algorithm is concerned and as specified by the insn_no_def() function, branching insns do not define anything. This includes call insns, even though one might argue that they define %r0. This means that the real problem is that zero extension kicks in at all. This happens because clear_caller_saved_regs() sets BPF_REG_0's subreg_def after global function calls. This can be fixed in many ways; this patch mimics what helper function call handling already does.

2021-02-15net: dsa: sja1105: make devlink property best_effort_vlan_filtering true by ↵Vladimir Oltean
default The sja1105 driver has a limitation, extensively described under Documentation/networking/dsa/sja1105.rst and Documentation/networking/devlink/sja1105.rst, which says that when the ports are under a bridge with vlan_filtering=1, traffic to and from the network stack is not possible, unless the driver-specific best_effort_vlan_filtering devlink parameter is enabled. For users, this creates a 'wtf' moment. They need to go to the documentation and find about the existence of this property, then maybe install devlink and set it to true. Having best_effort_vlan_filtering enabled by the kernel by default delays that 'wtf' moment (maybe up to the point that it never even happens). The user doesn't need to care that the driver supports addressing the ports individually by retagging VLAN IDs until he/she needs to use more than 32 VLAN IDs (since there can be at most 32 retagging rules). Only then do they need to think whether they need the full VLAN table, at the expense of no individual port addressing, or not. But the odds that an sja1105 user will need more than 32 VLANs terminated by the CPU is probably low. And, if we were to follow the principle that more advanced use cases should require more advanced preparation steps, then it makes more sense for ping to 'just work' while CPU termination of > 32 VLAN IDs to require a bit more forethought and possibly a driver-specific devlink param. So we should be able to safely change the default here, and make this driver act just a little bit more sanely out of the box.

2021-02-15net: caif: Use netif_rx_any_context().Sebastian Andrzej Siewior
The usage of in_interrupt() in non-core code is phased out. Ideally the information of the calling context should be passed by the callers or the functions be split as appropriate. The attempt to consolidate the code by passing an arguemnt or by distangling it failed due lack of knowledge about this driver and because the call chains are hard to follow. As a stop gap use netif_rx_any_context() which invokes the correct code path depending on context and confines the in_interrupt() usage to core code.

2021-02-15net: mscc: ocelot: avoid type promotion when calling ocelot_ifh_set_destVladimir Oltean
Smatch is confused by the fact that a 32-bit BIT(port) macro is passed as argument to the ocelot_ifh_set_dest function and warns: ocelot_xmit() warn: should '(((1))) << (dp->index)' be a 64 bit type? seville_xmit() warn: should '(((1))) << (dp->index)' be a 64 bit type? The destination port mask is copied into a 12-bit field of the packet, starting at bit offset 67 and ending at 56. So this DSA tagging protocol supports at most 12 bits, which is clearly less than 32. Attempting to send to a port number > 12 will cause the packing() call to truncate way before there will be 32-bit truncation due to type promotion of the BIT(port) argument towards u64. Therefore, smatch's fears that BIT(port) will do the wrong thing and cause unexpected truncation for "port" values >= 32 are unfounded. Nonetheless, let's silence the warning by explicitly passing an u64 value to ocelot_ifh_set_dest, such that the compiler does not need to do a questionable type promotion.

2021-02-15netfilter: nftables: introduce table ownershipPablo Neira Ayuso
A userspace daemon like firewalld might need to monitor for netlink updates to detect its ruleset removal by the (global) flush ruleset command to ensure ruleset persistency. This adds extra complexity from userspace and, for some little time, the firewall policy is not in place. This patch adds the NFT_TABLE_F_OWNER flag which allows a userspace program to own the table that creates in exclusivity. Tables that are owned... - can only be updated and removed by the owner, non-owners hit EPERM if they try to update it or remove it. - are destroyed when the owner closes the netlink socket or the process is gone (implicit netlink socket closure). - are skipped by the global flush ruleset command. - are listed in the global ruleset. The userspace process that sets on the NFT_TABLE_F_OWNER flag need to leave open the netlink socket. A new NFTA_TABLE_OWNER netlink attribute specifies the netlink port ID to identify the owner from userspace. This patch also updates error reporting when an unknown table flag is specified to change it from EINVAL to EOPNOTSUPP given that EINVAL is usually reserved to report for malformed netlink messages to userspace.

2021-02-15xen-blkback: fix error handling in xen_blkbk_map()Jan Beulich
The function uses a goto-based loop, which may lead to an earlier error getting discarded by a later iteration. Exit this ad-hoc loop when an error was encountered. The out-of-memory error path additionally fails to fill a structure field looked at by xen_blkbk_unmap_prepare() before inspecting the handle which does get properly set (to BLKBACK_INVALID_HANDLE). Since the earlier exiting from the ad-hoc loop requires the same field filling (invalidation) as that on the out-of-memory path, fold both paths. While doing so, drop the pr_alert(), as extra log messages aren't going to help the situation (the kernel will log oom conditions already anyway). This is XSA-365.

2021-02-15Xen/gntdev: correct error checking in gntdev_map_grant_pages()Jan Beulich
Failure of the kernel part of the mapping operation should also be indicated as an error to the caller, or else it may assume the respective kernel VA is okay to access. Furthermore gnttab_map_refs() failing still requires recording successfully mapped handles, so they can be unmapped subsequently. This in turn requires there to be a way to tell full hypercall failure from partial success - preset map_op status fields such that they won't "happen" to look as if the operation succeeded. Also again use GNTST_okay instead of implying its value (zero). This is part of XSA-361.

2021-02-15Xen/gntdev: correct dev_bus_addr handling in gntdev_map_grant_pages()Jan Beulich
We may not skip setting the field in the unmap structure when GNTMAP_device_map is in use - such an unmap would fail to release the respective resources (a page ref in the hypervisor). Otoh the field doesn't need setting at all when GNTMAP_device_map is not in use. To record the value for unmapping, we also better don't use our local p2m: In particular after a subsequent change it may not have got updated for all the batch elements. Instead it can simply be taken from the respective map's results. We can additionally avoid playing this game altogether for the kernel part of the mappings in (x86) PV mode. This is part of XSA-361.
