      netlabel: use domain based selectors when address based selectors are not available · 6a8b7f0c
      Paul Moore authored
      NetLabel has the ability to selectively assign network security labels
      to outbound traffic based on either the LSM's "domain" (different for
      each LSM), the network destination, or a combination of both.  Depending
      on the type of traffic, local or forwarded, and the type of traffic
      selector, domain or address based, different hooks are used to label the
      traffic; the goal being minimal overhead.
      
      Unfortunately, there is a bug such that a system using NetLabel domain
      based traffic selectors does not correctly label outbound local traffic
      that is not assigned to a socket.  The issue is that in these cases
      the associated NetLabel hook only looks at the address based selectors
      and not the domain based selectors.  This patch corrects this by
      checking both the domain and address based selectors so that the correct
      labeling is applied, regardless of the configuration type.
      
      In order to acomplish this fix, this patch also simplifies some of the
      NetLabel domainhash structures to use a more common outbound traffic
      mapping type: struct netlbl_dommap_def.  This simplifies some of the code
      in this patch and paves the way for further simplifications in the
      future.

      net: check net.core.somaxconn sysctl values · 5f671d6b
      Roman Gushchin authored
      It's possible to assign an invalid value to the net.core.somaxconn
      sysctl variable, because there is no checks at all.
      
      The sk_max_ack_backlog field of the sock structure is defined as
      unsigned short. Therefore, the backlog argument in inet_listen()
      shouldn't exceed USHRT_MAX. The backlog argument in the listen() syscall
      is truncated to the somaxconn value. So, the somaxconn value shouldn't
      exceed 65535 (USHRT_MAX).
      Also, negative values of somaxconn are meaningless.
      
      before:
      $ sysctl -w net.core.somaxconn=256
      net.core.somaxconn = 256
      $ sysctl -w net.core.somaxconn=65536
      net.core.somaxconn = 65536
      $ sysctl -w net.core.somaxconn=-100
      net.core.somaxconn = -100
      
      after:
      $ sysctl -w net.core.somaxconn=256
      net.core.somaxconn = 256
      $ sysctl -w net.core.somaxconn=65536
      error: "Invalid argument" setting key "net.core.somaxconn"
      $ sysctl -w net.core.somaxconn=-100
      error: "Invalid argument" setting key "net.core.somaxconn"
      
      Based on a prior patch from Changli Gao.

      timer routine checks the link status and if it's up calls

      htb: fix sign extension bug · cbd37556
      stephen hemminger authored
      When userspace passes a large priority value
      the assignment of the unsigned value hopt->prio
      to  signed int cl->prio causes cl->prio to become negative and the
      comparison is with TC_HTB_NUMPRIO is always false.
      
      The result is that HTB crashes by referencing outside
      the array when processing packets. With this patch the large value
      wraps around like other values outside the normal range.
