The only reason I can see for not calling capable\nis that it once appeared we were not in the same task as the caller which\nwould have made calling capable() impossible.\n\nIn the initial user_namespace the only difference between between\ncap_raised(current_cap(), CAP_SYS_ADMIN) and capable(CAP_SYS_ADMIN) are a\nfew sanity checks and the fact that capable(CAP_SYS_ADMIN) sets\nPF_SUPERPRIV if we use the capability.\n\nSince we are going to be using root privilege setting PF_SUPERPRIV seems\nthe right thing to do.\n\nThe motivation for this that patch is that in a child user namespace\ncap_raised(current_cap(),...) tests your capabilities with respect to that\nchild user namespace not capabilities in the initial user namespace and\nthus will allow processes that should be unprivielged to use the kernel\nservices that are only protected with cap_raised(current_cap(),..).\n\nTo fix possible user_namespace issues and to just clean up the code\nreplace cap_raised(current_cap(), CAP_SYS_ADMIN) with\ncapable(CAP_SYS_ADMIN).\n\nSigned-off-by: Eric W.

The current disk-timeout code works on top\nof the drbd_request objects. During attach we do not allow IO\nand therefore never generate a drbd_request object but block\nbefore that in drbd_make_request().\n\nThis patch adds the timeout to all drbd_md_sync_page_io().\n\nBefore this patch we used to go from D_ATTACHING directly\nto D_DISKLESS if IO failed during attach. We can no longer\ndo this since we have to stay in D_FAILED until all IO\nops issued to the backing device returned.\n\nSigned-off-by: Philipp Reisner \u003cphilipp.reisner@linbit.com\u003e\nSigned-off-by: Lars Ellenberg \u003clars.ellenberg@linbit.com\u003e\n" }, { "commit": "4afc433cf8066c112bd2bdd949d78ff8e8b4ba3f", "tree": "2919bdbaf204cb54b489988d1af2101f8d320af4", "parents": [ "545752d5d8a2e01b4fcb23a61ec732b2b26cbe1a" ], "author": { "name": "Philipp Reisner", "email": "philipp.reisner@linbit.com", "time": "Tue Dec 13 10:31:32 2011 +0100" }, "committer": { "name": "Philipp Reisner", "email": "philipp.reisner@linbit.com", "time": "Wed May 09 15:16:29 2012 +0200" }, "message": "drbd: Do not send state packets while lower than C_CONNECTED cstate\n\nI.e. in C_WF_REPORT_PARAMS or in C_WF_CONNECTION.\nSending may already work in these cstates, but the peer still expects\nthe HandShake / ConnectionFeatures packet.\n\nActually triggered by the Testuite on kugel.\n\nSigned-off-by: Philipp Reisner \u003cphilipp.reisner@linbit.com\u003e\nSigned-off-by: Lars Ellenberg \u003clars.ellenberg@linbit.com\u003e\n" }, { "commit": "545752d5d8a2e01b4fcb23a61ec732b2b26cbe1a", "tree": "1614e4de9034bb2135becfebacc20eda30b64576", "parents": [ "763eb63625a625e4d160cbb4cce2bcdb40141b97" ], "author": { "name": "Lars Ellenberg", "email": "lars.ellenberg@linbit.com", "time": "Mon Dec 05 14:39:25 2011 +0100" }, "committer": { "name": "Philipp Reisner", "email": "philipp.reisner@linbit.com", "time": "Wed May 09 15:16:01 2012 +0200" }, "message": "drbd: fix race between disconnect and receive_state\n\nIf the asender thread, or request_timer_fn(), or some other part of\nthe code, decided to drop the connection (because of timeout or other),\nbut the receiver just now was processing a P_STATE packet, there was a\nchance that receive_state() would do a hard state change\n\"re-establishing\" an already failed connection without additional handshake.\n\nLog excerpt:\n Remote failed to finish a request within ko-count * timeout\n peer( Secondary -\u003e Unknown ) conn( Connected -\u003e Timeout ) pdsk( UpToDate -\u003e DUnknown )\n asender terminated\n ...\n peer( Unknown -\u003e Secondary ) conn( Timeout -\u003e Connected ) pdsk( DUnknown -\u003e UpToDate ) peer_isp( 0 -\u003e 1 )\n ...\n Connection closed\n peer( Secondary -\u003e Unknown ) conn( Connected -\u003e Unconnected ) pdsk( UpToDate -\u003e DUnknown ) peer_isp( 1 -\u003e 0 )\n receiver terminated\n\nImpact:\nwhile the connection state is erroneously \"Connected\",\nrequests may be queued and even sent,\nwhich would never be acknowledged,\nand may have been missed by the cleanup.\nThese requests would never be completed.\n\nThe next drbd_suspend_io() will then lock up,\nwaiting forever for these requests to complete.\n\nFixed in several code paths:\n Make sure the connection state is NetworkFailure or worse\n before starting the cleanup in drbd_disconnect().\n This should make sure the cleanup won\u0027t miss any requests.\n\n Disallow receive_state() to \"upgrade\" the connection state\n from an error state.
