[PATCH 1/2] Define ENOAUTHSERVICE to indicate "Authentication service unavailable" [ver #2]

As the kernel has or will have filesystems (and possibly other services) that
want to obtain authentication tokens and/or encryption data on demand (via
GSSAPI for example), it would seem useful to provide an additional error code
to indicate a problem with the lookup, rather than overloading some other error
code.

We already have EKEYREJECTED, EKEYREVOKED and EKEYEXPIRED to indicate problems
with a token that we already have, but what if the authentication server just
isn't available?

Define ENOAUTHSERVICE to indicate "Authentication service unavailable".  This
can be used to indicate, for example, that an attempt was made by request_key()
to retrieve a key, but the authentication server (e.g. a KDC) it is supposed to
contact didn't answer or that it couldn't determine the location of a suitable
server.

One way this can be used is that the user of a network filesystem can get a TGT
from the KDC and stash it in their session keyring, then the filesystem can
attempt to automatically get a ticket for accessing the filesystem - but if the
server is uncontactable then the ticket can be negatively instantiated with
KEYCTL_REJECT, giving the error to be handed to future requests as
ENOAUTHSERVICE and a small timeout so that the key will expire from the cache
and allow a retry after a short while to prevent thrashing.

[Bug] epoll_wait return EPOLLOUT even with EPOLLET flag

Hi,

I am a linux user and I found some question when using epoll with EPOLLET.

My program's step:

1. create a socket (sfd) and connect to server
2. create epoll (efd)
3. add socket descriptor (sfd) to epoll (efd) with flag EPOLLET
4. get a EPOLLOUT event through epoll_wait

After that, the program will nerver get a EPOLLOUT event because ituse
EPOLLET mode (the same event will not be got twice)

BUT，when a message comes from server，the client socket will get aevent
and this event contains EPOLLOUT and EPOLLIN, looks epoll_waitreturn
too much events than it should

My question is: Is this a bug for epoll ?

Any reply will be appreciate.

sendmmsg(2) draft man pages

Hello Anton,

Stephan Mueller made an initial shot at a manual page for the
sendmmsg() syscall that you recently added to the kernel. This
inspired me to come up with a more complete version, which I'd like to
get reviewed before including in man-pages. Could you take a look
("man -l <file>") at the version below and let me know any errors or
omissions.

Thanks

Michael Kerrisk

REVIEW AND RESPOND


I have packaged a financial transaction that will benefit both of us. As a
regional manager, it's my duty to send in a financial report to my head
office in the capital city (Quito Ecuador) at the end of each year. In the
year 2009 i discovered that my branch made three million seven hundred and
fifty thousand dollar, which my head office doesn't know about. I have placed
the said funds in a suspense account without any beneficiary.

As an official of the bank I cannot be directly connected to the money. So i
need you to assist and receive this money into your account and 35% of the
total sum will be yours. There is no risk involved and it will be a bank to
bank transfer. All I need from you is to stand claim as the original
depositor of this fund and have my head office transfer the money to your account.

I will give you more details on how we can achieve it successfully once i
hear from you. Please contact me with this email address: taurinoalarico@...
