I propose to add the get\nability by using SO_ATTACH_FILTER in getsockopt. To be less\nirritating to eyes the SO_GET_FILTER alias to it is declared. This\nability is required by checkpoint-restore project to be able to\nsave full state of a socket.\n\nThere are two issues with getting filter back.\n\nFirst, kernel modifies the sock_filter-\u003ecode on filter load, thus in\norder to return the filter element back to user we have to decode it\ninto user-visible constants. Fortunately the modification in question\nis interconvertible.\n\nSecond, the BPF_S_ALU_DIV_K code modifies the command argument k to\nspeed up the run-time division by doing kernel_k \u003d reciprocal(user_k).\nBad news is that different user_k may result in same kernel_k, so we\ncan\u0027t get the original user_k back. Good news is that we don\u0027t have\nto do it. What we need to is calculate a user2_k so, that\n\n reciprocal(user2_k) \u003d\u003d reciprocal(user_k) \u003d\u003d kernel_k\n\ni.e. if it\u0027s re-loaded back the compiled again value will be exactly\nthe same as it was. That said, the user2_k can be calculated like this\n\n user2_k \u003d reciprocal(kernel_k)\n\nwith an exception, that if kernel_k \u003d\u003d 0, then user2_k \u003d\u003d 1.\n\nThe optlen argument is treated like this -- when zero, kernel returns\nthe amount of sock_fprog elements in filter, otherwise it should be\nlarge enough for the sock_fprog array.\n\nchanges since v1:\n* Declared SO_GET_FILTER in all arch headers\n* Added decode of vlan-tag codes\n\nSigned-off-by: Pavel Emelyanov \u003cxemul@parallels.com\u003e\nSigned-off-by: David S.
