A VSI handle is just a number the driver maintains to uniquely identify a VSI. A VSI handle is backed by a VSI number in the hardware. When interacting when the hardware, VSI handles are converted into VSI numbers. In commit 0f9d5027 ("ice: Refactor VSI allocation, deletion and rebuild flow"), VSI handles were introduced but it was used only when creating and deleting VSIs. This patch is part one of two patches that expands the use of VSI handles across the rest of the driver. Also in this patch, certain parts of the code had to be refactored to correctly use VSI handles. Signed-off-by:

In the recent TCP/EDT patch series, I switched TCP and sch_fq clocks from MONOTONIC to TAI, in order to meet the choice done earlier for sch_etf packet scheduler. But sure enough, this broke some setups were the TAI clock jumps forward (by almost 50 year...), as reported by Leonard Crestez. If we want to converge later, we'll probably need to add an skb field to differentiate the clock bases, or a socket option. In the meantime, an UDP application will need to use CLOCK_MONOTONIC base for its SCM_TXTIME timestamps if using fq packet scheduler. Fixes: 72b0094f ("tcp: switch tcp_clock_ns() to CLOCK_TAI base") Fixes: 142537e4 ("net_sched: sch_fq: switch to CLOCK_TAI") Fixes: fd2bca2a ("tcp: switch internal pacing timer to CLOCK_TAI") Signed-off-by:

TLS test cases splice_from_pipe, send_and_splice & recv_peek_multiple_records expect to receive a given nummber of bytes and then compare them against the number of bytes which were sent. Therefore, system call recv() must not return before receiving the requested number of bytes, otherwise the subsequent memcmp() fails. This patch passes MSG_WAITALL flag to recv() so that it does not return prematurely before requested number of bytes are copied to receive buffer. Signed-off-by:

The RSC feature -- a bit field "internal" was added here with total size unchanged: struct rndis_per_packet_info { u32 size; u32 type:31; u32 internal:1; u32 ppi_offset; }; On TX path, we put rndis msg into skb head room, which is not zeroed before passing to us. We do not use the "internal" field in TX path, but it may impact older hosts which use the entire 32 bits as "type". To fix the bug, this patch sets the field "internal" to zero.

Florian Fainelli says: ==================== net: systemport: Turn on offloads by default Up until now, we had added all the code necessary to turn on RX/TX checksum offloads at runtime, but there is no reason why they have to be disabled by default given that this gives a slight performance improvement. ==================== Signed-off-by: -

During driver resume and open, the HW may have lost its context/state, utilize bcm_sysport_set_features() to make sure we do restore the correct set of features that were previously configured. Signed-off-by:
-
Florian Fainelli authored
In preparation for unconditionally enabling TX and RX checksum offloads, refactor bcm_sysport_set_features() a bit such that __netdev_update_features() during register_netdev() can make sure that features are correctly programmed during network device registration. Since we can now be called during register_netdev() with clocks gated, we need to temporarily turn them on/off in order to have a successful register programming. We also move the CRC forward setting read into bcm_sysport_set_features() since priv->crc_fwd matters while turning on RX checksum offload, that way we are guaranteed they are in sync in case we ever add support for NETIF_F_RXFCS at some point in the future.

Johannes Berg says: ==================== netlink: extended attribute validation This adds further netlink attribute validation: * min/max/range validation * validation through a custom function pointer This is useful to * reduce boilerplate code in command handling code, if attributes are used commonly across different commands * get more extended ACK error messages/attribute pointers * ensure attributes are valid even when ignored (though this might be a problem when converting existing code) Changes since v1: * split off validate_type from type and use that for min/max/range and function; this is better because the range is limited to the range of s16 and so things like "u16 with minimum value 1" couldn't be expressed earlier * add macros for this, e.g. NLA_POLICY_MIN(NLA_U16, 1) for the case mentioned in the previous bullet Using this pretty much in all places where applicable in nl80211 reduces the code size there by about 1.8KiB, with just a minimal code increase in lib/nlattr.o. ==================== Signed-off-by: -
Johannes Berg authored
Add the ability to have an arbitrary validation function attached to a netlink policy that doesn't already use the validation_data pointer in another way. This can be useful to validate for example the content of a binary attribute, like in nl80211 the "(information) elements", which must be valid streams of "u8 type, u8 length, u8 value[length]".

Without further bloating the policy structs, we can overload the `validation_data' pointer with a struct of s16 min, max and use those to validate ranges in NLA_{U,S}{8,16,32,64} attributes. It may sound strange to validate NLA_U32 with a s16 max, but in many cases NLA_U32 is used for enums etc. since there's no size benefit in using a smaller attribute width anyway, due to netlink attribute alignment; in cases like that it's still useful, particularly when the attribute really transports an enum value. Doing so lets us remove quite a bit of validation code, if we can be sure that these attributes aren't used by userspace in places where they're ignored today. To achieve all this, split the 'type' field and introduce a new 'validation_type' field which indicates what further validation (beyond the validation prescribed by the type of the attribute) is done. This currently allows for no further validation (the default), as well as min, max and range checks. Signed-off-by: -

FD can be used in filtering the flows and deciding to drop the flow or forward it to paricular queue. Configuration consists of rules with input keys and actions.

Each flow director rule consists of input key and action. The input key is the condition for matching, includes tuples of L2/L3/L4 header. Action is the behaviour when a packet matches with the input key, such as drop the packet, or forward to a specified queue. The input key is stored in the tcam blocks, Each bit of input key can be masked. Signed-off-by:

Andrew Lunn says: ==================== Continue towards using linkmode in phylib These patches contain some further cleanup and helpers, and the first real patch towards using linkmode bitmaps in phylink. The macro magic in the RFC version has been replaced with run time initialisation. ==================== Signed-off-by: -
Andrew Lunn authored
This is one step in allowing phylib to make use of link_mode bitmaps, instead of u32 for supported and advertised features. Convert the phy drivers to use bitmaps to indicates the features they support. Build bitmap equivalents of the u32 values at runtime, and have the drivers point to the appropriate bitmap. These bitmaps are shared, and we don't want a driver to modify them. So mark them __ro_after_init. Within phylib, the features bitmap is currently turned back into a u32. This will be removed once the whole of phylib, and the drivers are converted to use bitmaps. Signed-off-by:

When SKBs are coalesced, we can have SKBs with different frag sizes. Some with PAGE_SIZE and some not with PAGE_SIZE. Since recv_skip_hint is always set to the full SKB size, it can overestimate the amount that should be read using normal read for coalesced packets. Change the recv_skip_hint so that it only includes the first frags that are not of PAGE_SIZE. Signed-off-by:
